A spring with a constant of #2/5 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #1 kg# and speed of #2 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
The moving object has a kinetic energy given by
All this energy is absorbed by the spring as potential energy as
