Consider the figure below. The spring is very stiff with a spring constant of 300 N/m. The ball shown in the figure collides with the block and the ball rebounds with a speed of 4 m/s to the left. Immediately after the collision the block is moving to the right. How far apart are the box and ball the first time the box reaches it's left most position? Be sure to solve algebraically before plugging in numbers! Note that mechanical energy is not conserved during the collision, the block is attached to the spring and the surface on which the block rests is frictionless. 15.0 kg 3.00 kg 8.00 m/s
