The spring shown below is connected to a wall and a 2 kg block. The block is subjected to a force of F = 500 N as shown. When s

= 0, the block is at rest and the spring is uncompressed. Assume the contact surface is smooth as the block travels 0.75 m to the right. Answer the following questions. a) At the point when the spring is compressed 0.75 m, how much potential energy is stored within the spring? (2points) b) How much work is done by the 500 N force of the 0.75 m the block travels? (2 points) c) What is the magnitude of velocity for the block at the moment it has traveled 0.75 m to the right? (2 points)
