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

A ball is projected with velocity (u) at an anle alpha with horizontal plane. What is its speed when it makes an angle theta whith the horizontal plane ?

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 horizontal distance 'd' from the wall is

A ball is projected with an velocity V_(0) at an angle of elevation 30^(@) . Mark of the correct statement.

A small ball thrown at an initial velocity v_(0) at an angle alpha to the horizontal strikes elastically with a smooth vertical wall moving towards it at a horizontal velocity v and returns to the point from which it was thrown. Determine the time t from the beginning of motions to the moment of impact with vertical wall. Neglect friction losses.

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 :
