THANK YOU MA'AM THIS IS REALLY HELPFUL 💗

a football is kicked at a certain angle above the horizontal. the vertical component of its initial velocity is 40m/s and the horizontal component is 50m/s Determine a. its time of flight b. the horizontal distance it travels; c. its initial velocity

[@meowmeow3136]

Maam patulong po please

[@meowmeow3136]

Maam kahit yung formula at given lang po

[@wellabasisto7443]

a. time of flight (total time = time up + time down) using the vertical motion of the projectile going up, you may compute time up using this formula t = -viy÷g = -40m/s ÷ -9.8m/s2 time up = 4.08s time up = time down so, total time = 4.08s + 4.08s = 8.16s b) horizontal distance it travels[max. dx(range)] dx = vixt; yung time n gagamitin dto ay total time dx = (50m/s)(8.16s) = 408m c. its initial velocity (vi) vi = √(vix)^2 + (viy)^2 = √(50m/s)^2 + (40m/s)^2 = √2 500m2/s2 + 1 600m2/s2 = √4 100m2/s2 vi = 64m/s

[@SIRK_ICE]

Pls. consider these comments with an open mind. 1) Your third statement (facts about projectiles)"The horizontal velocity is constant due to GRAVITY" contradicts the concept that the horizontal component of projectile motion is INDEPENDENT of its vertical component (gravity does NOT affect the horizontal velocity). The horizontal velocity is constant (zero acceleration) because there is NO horizontal net force acting on the body. It continues to move with a constant horizontal velocity because of its INERTIA in motion (1st law of motion). 2) When a projectile reaches the top of its trajectory, it does NOT stop momentarily because its resultant velocity is equal to its constant horizontal velocity (only the instantaneous vertical velocity becomes zero).

8:32 ma'am diko po gets bakit naging 160.745 ung answer:( pano po siya naging ganon? I tried to solve pero iba answer ko... pls help ma'am ty😊

sa calculator, (1) lagay mo 30sin25 then hit equals. (2) then click "x^2", then hit equals mkukuha mo n yung sagot ni mam n 160.745

Tanong po 10:43 Kung may t = 0 dapat parin gawin ang total time? Or direct na agad sa (30m/s)(cos 25°)(0)?

Kung may "when time is zero"
