A bullet of mass 20 g, travelling at a speed of 350 ms −1 , strikes a steel plate at an angle
of 30º with the plane of the plate. It ricochets off at the same angle, at a speed of
320 ms −1 . What is the magnitude of the impulse that the steel plate gives to the
projectile? If the collision with the plate takes place over a time ∆t = 10 −3 s, what is the
average force exerted by the plate on the bullet?
