#question.1) [chp 2; NC] You drop a superball from your dormitory window, a height, h=30 m, above the
ground. 1 s after this your friend shoots a superball straight upward toward the falling ball. Your
friends shot leaves from the ground at vo =20 m/s. (Neglect friction and air resistance.)
a) How long after you release your ball do the balls collide?
b) At what height above the ground do they collide?
c) Which object is moving faster at the moment of collision?
d) Sketch a space-time diagram for this event.
