3) [8 pts) A 12.0 kg box slides 4.00 m down a frictionless ramp as shown below, then collides with a spring whose spring constant is 500. N/m. a. What is the maximum compression of the spring? b. At what compression of the spring does the box have its maximum speed (Hint: find the position where the force on the box is zero)? c. What is the initial acceleration of the box when it starts back up the ramp after maximum compression? 4.0 m 30
