A block with a mass 3.7 kg is sitting on a frictionless ramp with a spring at rhe bottom that has a spring constant of 540 N/m. The angle of the ramp in respect to the horizontal is 36 degrees.  1) the block starts from rest and slides down the ramp a distance of 69cm before hitting the spring. how far is the spring compressed as the block comes to momentary rest? 2) after the block comes to rest the spring pushes the block back up the ramp. how fast is the block moving right after it comes off the spring.  3) what is the change in gravitational potential energy between the original positiion of the block at the top of the ramp and the position of the block when the spring is fully compressed?

Question

A block with a mass 3.7 kg is sitting on a frictionless ramp with a spring at rhe bottom that has a spring constant of 540 N/m. The angle of the ramp in respect to the horizontal is 36 degrees. 

1) the block starts from rest and slides down the ramp a distance of 69cm before hitting the spring. how far is the spring compressed as the block comes to momentary rest?

2) after the block comes to rest the spring pushes the block back up the ramp. how fast is the block moving right after it comes off the spring. 

3) what is the change in gravitational potential energy between the original positiion of the block at the top of the ramp and the position of the block when the spring is fully compressed?
