A bullet of mass m=.060 kg hits a 5.000 kg block with a initial speed of 225 m/s. The block is connected to a spring as shown in the Figure below. The friction between the block and the table is negligible. Upon impact the bullet bounces back from the box with a speed of 75 m/s.
a) Calculate the speed of the block right after the collision.
b) As a result of the collision the spring compresses to a maximum of 0.20 m. Find the spring constant.
c) Find the inelastic energy loss during the collision.
