A body of mass m slides without friction from rest at height H to a lower height h, where it encounters a horizontal spring with strength k. by how much does it compress?(adsbygoogle = window.adsbygoogle || []).push({});

To solve this i was wondering if we needed to take into account the changes in energy of the body. i.e 1/2 mv^2=mgh and if the force of the collision can be substitiuted into mg=kx?
