A particle strikes a horizontal smooth floor with a velocity a making an angle `theta` with the floor and rebounds with velocity `v` making an angle `phi` with the floor. If the coefficient of restitution between the particle and the floor is `e`, then

A particle of mass m strikes a horizontal smooth floor with velocity u making an angle theta with the floor and rebound with velocity v making an angle theta with the floor. The coefficient of restitution between the particle and the floor is e . Then

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 :
