Starting with an initial speed of 5.00 m/s at a height of 0.335 m, a 1.50-kg ball swings downward and strikes a 4.60-kg ball that is at rest, as the drawing shows.
(a) Using the principle of conservation of mechanical energy, find the speed of the 1.50-kg ball just before impact. m/s
(b) Assuming that the collision is elastic, find the velocities (magnitude and direction) of both balls just after the collision. m/s (1.50 kg-ball) m/s (4.60 kg-ball)
(c) How high does each ball swing after the collision, ignoring air resistance? m (1.50 kg-ball) m (4.60 kg-ball)
