You push a box of mass 19 kg with your car up to an icy hill slope of irregular shape to a height 5.8 m. The box has a speed 12 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 coming to a rest when hitting a box of mass 42 kg. The heavier box then falls off a sheer cliff to the ground (with no drag). (a) What is the speed of the heavier box as it flies off the top of the hill? (b) What is the coordinate form of the velocity of the heavier box just before hitting the ground? + (c) What is the vector form of the velocity of the heavier box just before hitting the ground? = ( ______ + 2)
