A spring with a constant of #3 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #6 kg# and speed of #8 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
We need the following formulae
Elastic potential energy for springs
we have an object of mass
it will have kinetic energy of
on collision with the spring all this will be given to the spring in terms of EPE
