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 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 ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at some distance from the point of projection and returns on the same level. Coefficient of restitution between the ball and the wall is e, then time taken in path AB and maximum height attained by the ball 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 .
