You push a box of mass 20.6 kg with your car up to an icy hill slope of irregular shape to a height 4.3 m. The box has a speed 12.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before sliding into a box larger box of mass 19 kg. The boxes then fall off a sheer cliff together to the ground (with no drag).
