Question
Repeat Example 10.15 in which the disk strikes and adheres to the stick 0.100 m from the nail.

Example 10.15

Suppose the disk in Figure 10.26 has a mass of 50.0 g and an initial velocity of 30.0 m/s when it strikes the stick that is 1.20 m long and 2.00 kg.
1. What is the angular velocity of the two after the collision?
2. What is the kinetic energy before and after the collision?
3. What is the total linear momentum before and after the collision?
