Starting with an initial speed of 6.63 m/s at a height of 0.473 m, a 1.67-kg ball swings downward and strikes a 5.91-kg ball that is at rest, as the drawing shows.

(a) Using the principle of conservation of mechanical energy, find the speed of the 1.67-kg ball just before impact.

(b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 1.67-kg ball just after the collision.

(c) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 5.91-kg ball just after the collision.

(d) How high does the 1.67-kg ball swing after the collision, ignoring air resistance?

(e) How high does the 5.91-kg ball swing after the collision, ignoring air resistance?
