A spring with a constant of #8 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #7 kg# and speed of #9 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
The compression of spring would be 8.42 m
Here the kinetic energy of the moving body = potential energy stored in the compressed spring due to collision
PE stored in the spring =
equating this two we hqve
