60. (a) Let m 1 be the mass of one sphere, v 1 i be its velocity before the collision, and v 1 f be its velocity after the collision. Let m 2 be the mass of the other sphere, v 2 i be its velocity before the collision, and v 2 f be its velocity after the collision. Then, according to Eq. 9-75, v mm v m v fii 1 12 1 2 2 2 = + + + . Suppose sphere 1 is originally traveling in the positive direction and is at rest after the collision. Sphere 2 is originally traveling in the negative direction. Replace
