Physics

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 The wheel is a solid disk with mass M = 2.29 kg and radius R = 1.:6 cm. The wheel rotates freely about an axis through its center and out of the plane shown in the 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 234 m/s.

asked by Lindsay
  1. (a) What is the angular speed (rad/s) of the wheel just after the bullet leaves it?
    (b) How much kinetic energy (J) was lost in the collision?
