A block of mass 2.1 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 525 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 12 degrees.
a. The block, starting from rest, slides down the ramp a distance 68 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes back to momentary rest?
b. After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring?
c. What is the change of the gravitational potential eneregy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?
One end of a 10-cm-long spring is attached to the ceiling. When a 2.0 kg mass is hung from the other end, the spring stretches to a length of 15 cm.a. What is the spring constant?b. How long is the spring when a 3.0 kg mass is suspended from it?

Initially the block is released from rest when the spring is compressed by a distance 0.3 m. a. What is the speed of the block when the block loses contact with the spring?

The solutions give the answer to be V1f=0.20 m/s, v2f=2.75 m/s for part A. For part B the solutions give the answer to be x=0.22 for maximum compression for the spring.
