A bullet of mass m and velocity v hits a block of mass M and gets stuck in it. The block is initially at rest on a frictionless table. The spring constant of the spring is k, see figure. 1. What will be the frequency of the oscillations after the bullet is stuck in the block? 2. What will be the amplitude of the oscillations
