Question

A small solid sphere of unit mass, strikes a horizontal smooth floor with a velocity $u = 10 m / s$ , making an angle $θ = 6 0^{\circ}$ with the floor and rebounds with velocity v making an angle $ϕ$ with the floor. If the coefficient of restitution between the particle and the floor is $e = 0.6$ , then :
