Problem Set 11 1. Two masses undergo a front-to-back collision. The mass m has an initial velocity 2v o and the mass 2m has an initial velocity v o . After the collision, they stick together, forming a compound system. Find a. The initial kinetic energy b. The final momentum of the compound system c. The final kinetic energy of the compound system d. The final velocity of the compound system 2. A water molecule consists of an oxygen atom with two hydrogen atoms bound to it. The angle between the two bonds is 106 o . If each bond is 0.116nm long, how far from the oxygen atom is the center of mass of the molecule? Take the mass of an oxygen atom to be 16 times the mass of a hydrogen atom. 3. A 58.3 kg person throws a 0.051 kg snowball forward with a ground speed of 30.8 m/s. A second person, of mass 45.6 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.67 m/s, and the second person is initially at rest. What is the velocity of the first person immediately after the snowball is thrown? Disregard friction
