A ball is released from point A as shown in figure. The ball leaves the track at B. All surfaces are smooth.

If track makes an angle `30^(@)` with horizontal at B, then maximum height attained by ball will be

A ball is released from point A as shown in figure. The ball leaves the track at B. All surfaces are smooth. Let h be the maximum height from ground reached by ball after leaving track at B. Then,

A ball is projected as shown in figure. The ball will return to point:

A ball is released from top of the smooth vertical, when i just leaves the contract form inner surface of the tube

A ball is projected at an angle 60^(@) with the horizontal with speed 30 m/s. What will be the speed of the ball when it makes an angle 45^(@) with the horizontal ?

A ball is projected from the point O with velocity 20 m//s at an angle of 60^(@) with horizontal as shown in figure. At highest point of its trajectory it strikes a smooth plane of inclination 30^(@) at point A. The collision is perfectly inelastic. The maximum height from the ground attained by the ball is (g=10 m//s^(2))

Two identical balls A and B are released from the position shown in Fig. They collide elastically with each other on the horizontal portion. The ratio of heights attained by A and B after collision is (neglect friction)

A ball is released from point A. During its motion ball takes two seconds from B to C Find the time taken by ball from A to C. .
