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

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

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

A ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at a distance a from the point of projection and returns to its original position. Find the coefficient of restitution between the ball and the wall.

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 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 projectile, thrown with velocity v_(0) at an angle alpha to the horizontal, has a range R. it will strike a vertical wall at a distance R//2 from the point of projection with a speed of

A ball is projected horizontally with a speed v from the top of the plane inclined at an angle 45^(@) with the horizontal. How far from the point of projection will the ball strikes the plane?

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 :
