Question:

A small ideal mirror of mass m = 10 mg is suspended by a weightless thread of length l = 10 cm. Find the angle through which the thread will be deflected when a short laser pulse with energy E = 13J is shot in the horizontal direction at right angles to the mirror. Where does the mirror get its kinetic energy?
