Problem
A bullet of mass 5.0g enters a stationary wooden block of mass 1.0kg with a speed of 300ms−1, emerges from the opposite side with a speed of 100ms−1, and remains inside the block for 2.0ms. Neglect any other external forces.
(i) Calculate the magnitude and direction of the average force exerted by the block on the bullet while it is inside.
(ii) State the magnitude of the average force exerted by the bullet on the block during the same interval.
