A black of mass m=750g is released from rest and slides down a frictionless track of height h=55.2cm. At the bottom of the track the block slides freely along a horizontal table until it hits a spring attached to a heavy, immovable wall. The spring compressed by 2.64cm at the maximum compression. What is the value of the spring constant k?

Initially the mass had Potential Energy (PE) due to it's elevation. At the end of ...
Solution Summary
At the end of the motion, all this PE is converted into stored energy in the spring. This solution includes calculations.
