[@Mr_flash_videos]

Sir can we do it with shm

By taking two projection in x, y axis

[@ujjwalsingh3814]

But sir isme to solution galat ho gaya na. Agar boy ko ball catch karni he to uske liye ball ko wapas land bhi to karna padega. Matlab ball ki to resultant veloicity ki range he usko exact circumference pe khatam bhi to hona padega. aisa bhi to ho sakta he ki ball circumference tak pahuchne se pehle he land kar jae. To sir mai finally keh raha tha ki isme ek aur eqaution banegi jo Resultant velocity ko uski projectile ki direction me karegi => 2 * tan⁻¹(v/✓2Rw) = theta

[@m.a.y.u.k.h]

I actually equated the PM distance ,means the (root R^2w^2+v^2/2 )*v/root 2 *g =PM .PM is calculated from traingle law PM/sin wT =R/sin (180-wT)/2 ,Where T is v/root 2 *g

9:02 sir Person is in touch with table which means he doing circular motion also that's why you added linear velocity due to circular motion but the ball is in air and have only projection velocity not Circular velocity which cause ball to move towards centre only, it means person can catch only ball opposite side of daimeter. WHY YOU ADDED CIRCULAR VELOCITY TO BALL ALSO. I MAY WRONG?PLZ EXPLAIN SIR? How ball also has rw velocity?

[@ShivanshuMishra398]

Yes, sir table is doing circular motion not the ball...why you added linear velocity due to circular motion in ball.?

Ig the disc was already rotating before the boy even threw the ball, so just imagine yourself instead of the boy and it actually does make sense

[@Khokalaa]

@@ninja_42 yes, boy do circular motion and have linear velocity with wr but when you throw the ball in air it was not follow you because it has not circular velocity.

sir i was able to get the idea of that resultant velocity thing but can't get into PM and time of flight part. I'll try my best to evolve my thinking. Thanks for showing us the approach towards jee adv qs. Edit : PM = range of the projectile

[@sudarshan1793]

why resultant velocity is not included in time of flight it seems that tangential velocity only affect range and direction of projectile not time of flight

[@YouNight69]

I was able to think most part about it the mistake i made tht i thought it will catcht the ball at other point of circumference i mean I considered theta 180 degree and GOT wrong thank you sir for this amazing perspective!!

[@avigorai1644]

I feel lucky to have a mentor like you, At the same time i feel jealous that it is available on youtube and it is increasing competition day by day.

[@Namchha1]

Actually, for the boy to catch the ball, both of their x and y coordinates at time t must be identical. However, the boy's velocity in the negative y direction is always decreasing while the ball's vertical component of velocity is constant. This implies that the displacement in the negative y direction of the ball will forever be greater than that of the boy and hence, they can never be at the same position at time t which is not 0. I have mathematically analysed the result ashish sir derived in this video and can confidently say that the derived equation has no solution(v) for all real values of w and r which are constants in our equation.

[@abhayprajapati2485]

But I think that when the ball will actually complete its range then automatically x and y coordinates will match to that of the person at the same time

[@gourik1929]

You are correct When we look at in in only dimension (eyes pointing towards +ve x axis)we observe that always the ball will be ahead of the boy along -ve y. So they can never coincide

[@prikshitkhyalia8054]

You are correct. I have not analysed it mathematically but I was able to think the same. I was searching such type of comment and found yours. Thankyou.

[@darshan5044]

Exactly. I was just so confused how it could be even possible without having the boy _throw_ the ball in the +ve y direction. Without a throw in the +ve y direction the ball will always go farther than the boy in the y direction, hence never meeting at the same time and point in space after t=0. Thanks for writing the comment, I do not feel left out.

[@NishithDubey]

Sir centrifugal force bhi to lag rahi h?????

[@aadi7529]

In the last question, taking angle OPM as theta , we can get something more definitive, since tantheta = root2 wr/v , then angle POM is -tan 2theta

[@WhiteR9se]

you could look at this question in another way from the person's perspective and think of the disc to be stationary. then the person looks to throw the ball not at the centre but somewhere at the circumference to another person. and the v(h) as sir wrote it would be the only velocity and not a resultant one. the angle of inclination of the projectile would be same (45 degrees).

[@physicsgalaxyworld]

No. In person's frame what you've written is not correct because ball will experience Coriolis force in frame of disc... think again on this !

Sir can't we just simply use concept of relative motion Like at t=0 and t=final the displacement of ball wrt boy should be 0 For ball by vector laws components along x axis we have Rw of ball and -Rw of boy which cancels out In y axis we have vcos45 and deacceleration of -w²r since boy is moving with centripetal acceleration which will be parted to ball in his frame in -y axis In z axis we have vsin45 and g We don't care about the z axis but in y axis the displacement should be 0 so by 2nd equation of motion we can find time of 0 displacement which is √2v/w²r By this time we can calculate theta and other things

i was able to grab the theory of the question but now i am curious as this is an interesting question. now i am this train of thought : if we throw the ball towards the centre with enough velocity and the moment we throw the ball, the horizontal disc starts to accelerate, would it be possible to catch the ball diametrically. i solved theta for 180 degrees in this equation and as far as my math took me, it was not possible( for constant omega).

[@YouNight69]

same bro I took theta 180 degree (got wrong) then reconsidered to some small theta !!

[@snehapeter4686]

Hmm i guess you can if the ball was thrown just before disc started rotating and then disc had enough linear velocity for boy to reach and catch on time.. But if it was thrown exactly whe disc started rotating, you migh get what you want if the ball is thrown with rw in the opposite direction of rotation, making a required angle in that direction to cancel out velocity component due to rotating disc

Sir, your question is wrong ❌❌❌❌as there will be no solution. Because the ball has wr velocity in downward direction at the same time boy has wr velocity but on circular path so at any given time the downward displacement of ball will be greater than boy, so he would never be able to catch the ball. A correction can be made if he throws the ball by aiming at a point which is above the center O as then the downward velocity would decrease and the boy can catch the ball.

Sir correct me if i am wrong but if we take that man rotated by an angle theta and then write his x and y direction displacement in terms of Rcostheta and Rsintheta then correlating these displacements with the displacement of our projectile as final coordinate will be same , we can then use sin2theta + cos2theta = 1 And find the value of v in proper terms of w , R and g .

I have a doubt and any sort of assistance and constructive criticism will be appreciated. How is it even possible that the boy catches the thrown ball? Considering the plane of the board as a plane of a compass, as the ball is thrown, due to the translational velocity which has towards the south, it moves south a certain distance during this flight. The southward velocity of the ball remains constant. in the same time interval, P has to move a greater distance than the ball(in the south direction) whilst moving with the same speed as the ball to reach the point where the ball falls.. in such a situation, how is it even possible that P and the ball reach that point at the same time??
