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 ?

An inelastic ball is projetced with a velocity 'u' at an angle 'alpha' to the horizontal, towards a wall distant 'd' from the point of projection. After collision the ball returns to the point of projection (Co-efficient of restitution between sphere and wall is 'e' ) If the line joining the point of projection and the point of impact makes an angle 'theta' with the horizontal, then tan theta is

An inelastic ball is projetced with a velocity 'u' at an angle 'alpha' to the horizontal, towards a wall distant 'd' from the point of projection. After collision the ball returns to the point of projection (Co-efficient of restitution between sphere and wall is 'e' ) The total time of journey of the ball is

After collision the ball returns to the point of projection (Co-efficient of restitution between sphere and wall is 'e' ) The horizontal distance 'd' from the wall is

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 .

A ball is projected from ground with a velocity V at an angle theta to the vertical. On its path it makes an elastic collision with a vertical wall and returns to ground. The total time of flight of the ball is

A ball is projected with initial velocity u at an angle theta to the horizontal. Then horizontal displacement covered by ball as it collides third time to the ground would be, if coefficient of restitution is e :

A ball is thrown with the velocity u at an angle of alpha to the horizon. Find (i) the height of which the ball will rise to (ii) the distance x from the point of projection to the point where it reaches to the ground and (iii) the time during which the ball will be in motion (neglect the air resistance ).
