Starting with an initial speed of 5.00m/s at a height of 0.300 m, a1.50 kg ball swings downward andstrikes a 4.40 kg ball that is atrest, as the drawing shows.

(a) Using theprinciple of conservation of mechanical energy, find the speed ofthe 1.50 kg ball just beforeimpact.

(b) Assuming that the collision is elastic, find the velocities(magnitude and direction) of both balls just after thecollision.
m/s (1.50 kg ball)
m/s (4.40 kg ball)

(c) How high does each ball swing after the collision, ignoring airresistance?
m (1.50 kg ball)
m (4.40 kg ball)
