A sphere strikes a wall and rebounds with coefficient of restitution `(1)/(3)`. If it rebounds with a velocity of `0.1 m//sec` at an angle of `60^(@)` to the normal to the wall, the loss of kinetic energy is :

A body falling with a speed of 2m/s strikes the floor and rebounds with a speed of 1 m/s. The loss of kinetic energy is

A body falls on a surface of coefficient of restitution 0.6 from a height of 1 m . Then the body rebounds to a height of

A body falls on a surface of coefficient of restitution 0.6 from a height of 1 m . Then the body rebounds to a height of

A ball of mass 500 gram strikes a wall with a velocity of 80 m/s and rebounds with the same velocity. If the tme of contact is 1/30 sec, then the force exerted by the ball on the wall is

A ball of mass 0.1 kg strikes a wall normally with a speed of 30 m s ^( - 1 ) and rebounds with a speed of 20 ms ^( - 1 ) . The impulse of the force exerted by the wall on the ball is

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 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 particle strikes a smooth horizontal surface at an angle of 45^(@) with a velocity of 100m//s and rebounds. If the coefficient of restitution between the floor and the particle is 0.57 then the angle which the velocity of the particle after it rebounds will make with the floor is
