Answer of last question: Given, a = x² We know that a = dv/dt a = dv/dx × dx/dt a = v dv/dx v dv = a dx v dv = x² dx Integrating the above equation; v²/2 = x³/3 + C ... (1) Given when x = 0, v = 0 Putting in Eq. (1), 0 = 0 + C C = 0 Putting in Eq. (1), v²/2 = x³/3 At x = 2 m, v²/2 = 8/3 v² = 16/3 v = ± 4/√3

I provide here solution 👇 a = x^2 dv/dt = x^2 (dv/dx).(dx/dt) = x^2 (dv/dx) . v= x^2 vdv = x^2 dx Int ( vdv = x^2 dx) v^2 /2 =x^3 /3 +c at x=0 the particle at rest hence v=0 Hence c=0 v^2 /2 =x^3 /3 v^2 =x^3 ( 2/3) At x= 2 v^2 = 8.2/3 v= √16/3 v =4/√3 😅

Sir muje aapke vajah se hi physics mein maza aaraha hai

[@aslahaachu4542]

Last question answer is a=dv/dt dv/dt=x² dv/dx×dx/dt =x² dv/dx×V=x² Vdv=x²dx Integrating both sides V²/2=x³/3+C x=0(given) V=0(given) Applying in EQ.=>C=0 Therefore, V²/2=x³/3 If x=2m V²=(2³/3)×2 V=√(8×2/3) V=√(4×4/3) V=4/√3 m/s OR V= 4√3/3m/s This is the method😊

[@priyanshramrakhyani4872]

Answer is 4/√3. Explanation - a = (dv/dx)(dx/dt) a = (v)dv/dx a dx = v dv Integrating both sides, we get, x^3/3 + c1 = v^2 /2 + c2 After applying the condition we will find that c1 = c2 So, x^3/3 = v^2/2 v^2 = 8 * 2 / 3 v^2 = 16/3 v = √16/√3 v = 4/√3 or v = 4√3/3. Thanks.

Why are KZbin teachers always better than the actual ones ... Why can't this kind of amazing ones actually be teaching us in person

[@ginger0403]

You're not supposed to disrespect the teacher who're actually spending their time and effort on teaching you. True, they might not be making as much efforts as some other teachers but that doesn't exclude the fact that they actually taught you alot of things which you wouldn't have known otherwise. Also, as for KZbin teachers, They're also teaching students and have taught many students in past. So it isn't essentially right to label them as 'KZbin teachers' while comparing them with yet another disturbing term 'Actual teachers'. It's best to not complain and get knowledge from wherever you're able to.

[@semaljohari9531]

@@ginger0403 Yeah, students who study from KZbin seem to overlook the fact that there are several teachers whom students are paying for in school and coaching and they're also putting in equal efforts. If students are not able to grasp what those teachers are teaching, they can discontinue their coaching and study solely from KZbin. But disrespecting those teachers just because these students are not able to understand because of their efforts is indubitably deplorable!

Sooooo if we double differentiate Displacement we get acceleration soo f(x)= ? f'(x) = ? f''(x) = x²(given) So integrating x² f'(x) = x³/3 + C When x = 0 body is at rest so v = 0 so v = x³/3 + C 0 = 0+ C C= 0 So v = x³/3 Velocity at x = 2 8/3 m/s
