A spring of stiffness 330 kg/s^2 separates two blocks, the left having a mass 560 g and the right having a mass 260 g. You push the boxes towards each other, compressing the spring by a distance 22 cm, and then let them go.
a. How much work do you do in compressing the block?
b. What is the magnitude of the momentum of the left block after leaving the spring?
c. What is the speed of the left block?
d. What is the speed of the right block?
