A ball is thrown onto a rough floor at an angle θ. If it rebounds at an angle ϕ and the coefficient of kinetic friction is μ. determine the coefficient of restitution e. Neglect the size of the ball. Hint: Show that during impact the average impulses in the x and y directions are related by Ix = μIy Since the time of impact is the same, Fx. Δt = μFy Δt or Fx = μFy.
