Question

A pulsed laser fires a 1000 MW pulse of 208 ns duration at a small object that has a mass equal to 10 mg and is suspended by a fine fiber that is 3.79 cm long. If the radiation is completely absorbed by the object, what is the maximum angle of deflection of this pendulum? (Think of the system as a ballistic pendulum and assume the small object was hanging vertically before the radiation hit it.)
