A ball strikes a wall with a velocity `vecu` at an angle `theta` with the normal to the wall surface. and rebounds from it at an angle `beta` with the surface. Then

A ball strikes a smooth horizontal floor at an angle alpha with the normal to the surface and after rebounding from the floor , ball moves at an angle beta with the normal . Find the relation between alpha and beta if coefficient of elasticity is e .

A ball of mass 600 gm strikes a wall with a velocity of 5 ms^(-1) at an angle 30" with the wall and rebounds with the same speed at the same angle with the wall. The change in momentum of the ball is, (in kg ms^(-1) )

A small ball of mass m collides with as rough wal having coeficient of friction mu at an angle theta with the normal to the wall. If after collision the ball moves wilth angle alpha with the normal to the wall and the coefficient of restitution is e , then find the reflected velocity v of the ball just after collision.
