Question

A uniform stick 1.4m long with a total mass of 300g is pivoted at its center. A 4.0-g bullet is shot through the stick midway between the pivot and one end The bullet approaches at 250 m/s and leaves at 140 m/s. (Figure 1)

With what angular speed is the stick spinning after the collision?

(Figure 1) oemga = ___________rad/s With what angular speed is the stick spinning after the collision?

Explanation / Answer

When bullet hits the stick, total momentum of the system will remain same but individual momentum will change and can be find as
