A bullet of mass 5.0 g and velocity 330 m/s passes through a wheel at rest. The wheel is a
solid disk of mass 2 kg and radius 18 cm. The bullet passes through the wheel at a
perpendicular distance of 15 cm from the centre and the bullet's final velocity is 220 m/s.
What are the wheel's angular velocity, angular momentum and kinetic energy? Is the
energy of the motion conserved?
