You and a friend are standing at the edge of a snowcovered cliff. At the same time, you throw a snowball straight upward with a speed of 8.0 m/s over the edge of the cliff and your friend throws a snowball straight downward over the edge of the cliff with the same speed. Your snowball is twice as heavy as your friend's. Neglecting air resistance, which snowball will hit the ground first, and which will have the greater speed?
