A steel ball strikes a fixed smooth steel plate placed on a horizontal surface atan angle `theta` with the vertical. If the coefficient of restitution is e, the angle at which the rebound will take place is:

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

A particle strikes a horizontal frictionless floor with a speed u, at an angle theta with the vertical, and rebounds with a speed upsilon , at an angle phi with the vertical. The coefficient of restitution between the particle and the floor is e. The angle phi is equal to :

A ball is projected in a direction inclined to the vertical and bounces on a smooth horizontal plane. The range of one rebound is R . If the coefficient of restitution is e , then range of the next rebound is
