Answer to Question #69144 in Mechanics | Relativity for Simanchal Sahoo

Question

A bullet of mass 20 g, travelling at a speed of 350 m/s, 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 of320 m/s . 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 theaverage force exerted by the plate on the bullet?
