An ideal weightless spring with k=340 N/m is compressed by 10 cm from its equilibrium position. The axis of the spring is horizontal. A 0.2 kg marble is placed at the end of the spring and released horizontally on a frictionless surface.

a. What is the speed of the marble when the compression of the spring is 2 cm?

b. What is the maximum speed of the marble?

c. What will happen if the marble hits another stationary marble with the same mass?
