Question

A bullet with mass 20 grams and velocity 100 m/s collides with a wooden block of mass 2 kg. The wooden block is initially at rest, and is connected to a spring with k = 800 N/m. The other end of the spring is attached to an immovable wall. What is the maximum compression of the spring?

Note: You may assume that the spring is massless and that the collision between the bullet and the wooden block is completely inelastic

Explanation / Answer

initial momentum p = mv = 0.02kg * 100m/s = 2 kg
