Transcribed Image Text:You push a box of mass 21.4 kg with your car up to an icy hill slope of irregular shape to a height 5.1 m. The box has a speed 13.3 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 elastically colliding with a smaller box of mass 14 kg. The
boxes then fall off a sheer cliff individually to the ground (with no drag).
(a) How far from the cliff does the heavier box hit the ground?
(b) What is the direction of motion of the heavier box as it hits the ground?
