Homework Help: Physics Angular Momentum

Posted by jhay on Monday, July 11, 2011 at 6:46pm.

A bullet with a mass m = 4.83 g and initial speed of 330 m/s passes through a wheel which is initially at rest as in the gure. The wheel is a solid disk with mass M = 2.29 kg and radius R = 18.6 cm The wheel rotates freely about an axis through its center and out of the plane shown in the gure. The bullet passes through the wheel at a perpendicular distance 14.8 cm from the center. After passing through the wheel it has a speed of 201 m/s.

1) What is the angular speed (rad/s) of the wheel just after the bullet leaves it?

2) How much kinetic energy (J) was lost in the collision?
