Question: A ball is thrown onto a rough floor at an angle of θ = 45o. If it rebounds at the same angle = 45o, determine

A ball is thrown onto a rough floor at an angle of θ = 45o. If it rebounds at the same angle ǿ = 45o, determine the coefficient of kinetic friction between the floor and the ball. The coefficient of restitution is e = 0.6. Hint: Show that during impact, the average impulses in the x and y directions are related by 1x = μly. Since the time of impact is the same, FxΔt = μFy Δt or Fx = μFy
