by a spring with a stiffness of 2 N/mm, as shown in the figure below. A bullet with a weight of 2 N is fired at a speed of 20 m/s into a speed of 20 m/s into the block and sinks into it. Assuming that all the momentum of the bullet is transferred to the block, the motion of the bullet is entirely transferred to the block at the moment of impact, we ask to calculate the maximum displacement of the block a) neglecting damping and b) assuming that the damping is 10% critical

Question
A block of wood with a weight of 30 N is held by a spring with a stiffness of 2 N/mm, as shown in the figure below. A bullet with a weight of 2 N is fired at a speed of 20 m/s into a speed of 20 m/s into the block and sinks into it. Assuming that all the momentum of the bullet is transferred to the block, the motion of the bullet is entirely transferred to the block at the moment of impact, we ask to calculate the maximum displacement of the block a) neglecting damping and b) assuming that the damping is 10% critical.
