A person projected a small ball with speed U along the floor from
point A. If x = 3R, determine the required speed U so that the ball

return to A after moving the circular surface in the vertical plane from

B to C and becoming projectile at C.

Show answer and solution
V2 = V2 - 4gR
3R = V [IMAGE] V2 = U2 - 2g2R

U2 = 9gR / 4 + 4gR

U2 = 25 gR / 4

U =[IMAGE] TOPIC: WPE

SUB TOPIC: VERTICAL CIRCULAR MOTION
