Q. The flywheel of an engine has a moment of inertia 2.40- {rm kg} cdot {rm m}^{2} about its rotation axis. What is its final kinetic energy?

Q. A 5g lead bullet travelling at 370-m/s is stopped by a large tree. If half the kinetic energy of the bullet is transformed into internal energy and remains with the bullet whilst the other half is transmitted to the tree, what is the increase in temperature of bullet?
