A spring with a constant of #12 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #8 kg# and speed of #12 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
Well,here,during the compression,the kinetic energy of the object is transferred to the spring which is stored in it as elastic potential energy.
So,we can say,
So,putting the given values we get,
