A ball is thrown onto a rough floor at an angle of θ. If it rebounds at the same angle φ , determine the coefficient of kinetic friction between the floor and the ball. The coefficient of restitution is e. Hint: Show that during impact, the average impulses in the x and y directions are related by { I }_{ x } = μ { I }_{ y } . Since the time of impact is the same, { F }_{ x } Δt = μ { F }_{ y } Δt or { F }_{ x } = μ { F }_{ y } .
