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 projectile is thrown upward with a velocity v_(0) at an angle alpha to the horizontal. The change in velocity of the projectile when it strikes the same horizontal plane is

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 girl throws a ball with an initial velocity v at an angle 45^@ . The ball strikes a smooth vertical wall at a horizontal distance d from the girl and after rebound returns to her hands. What is the coefficient of restitution between wall and ball ? (v^2 gt dg)

A particle is thrown vertically upwards with a velocity v . It returns to the ground in time T. which of the following graphs correctly represents the motion ?

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

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

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 particle of mass m and charge q is thrown with initial velocity v_(0) at an angle with the horizontal. In space there exist an electric field of strength E at angle beta with the downward vertical away from the point of projection. Find the time of flight and range of projectile on horizontal ground
