You push a box of mass 24.9 kg with your car up to an icy hill slope of irregular shape to a height 4.4 m. the box has a speed 14 m/s when it starts up the hill, the same time that you brake. it then rises up to the top (with no friction) before immediately falling off a sheer cliff to the ground (with no drag).
(a) what is the speed of the box at the top of the hill?
(b) what is the direction (unit vector) of the box's velocity just before hitting the ground?
