A small ball is rolled with speed u from point A along a smooth circular track as shown in Fig. 3E.33. If `x = 3R`, determine the required speed u so that the ball returns to A, the point of projection. What is the minimum value of x for which the ball can reach the point of projection ?

A small ball is rolled with speed u from piont A along a smooth circular track as shown in figure. If x=3R , then Determine the required speed u so that the ball returns to A, the point of projection after passing through C, the highest point.

A small ball is rolled with speed u from point A along a smooth circular track as shown in figure. If x=3R , then What is the minimum value of x for which the ball can reach the point of projection after reaching C?

The value of u so that the ball reaches at point A (g = 10m/s2)

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 surace in the vertical plane from B to C and becoming projectile at C.

A ball is projected with velocity v_(0) at an angle alpha to the horizonal, towards a smooth wall which appraches the ball. With velocity u. After collision the ball retraces its path to the point of projection . What is the time t taken by the ball form the instant of projection to point of impact ?

A small ball is projected with a velocity u at some angle with horizontal towards a smooth vertical wall at a distance d from the point of projection after rebounding from the wall . If e is the coefficient of restitution then find maximum distance d for which ball may return to point of projection .

From a point on smooth floor of a room a toy ball is shot to hit a wall. The ball then returns back to the point of projection. If the time taken by ball in returining is twice the time taken in reaching the wall find the coefficient of restitution:

A small ball is pushed from a height h along a smooth hemispherical bowl of rodius R. With what speed should the ball be pushed so that it just reaches the top of the opposite end of the bowl?
