two blocks are held together with a compressed spring between them on the surface of a slippery table .one block has three times the inertia of the other .when the blocks are released ,the spring pushes them away from each other .what is the ratio of their kinetic energies after the release?
Answers: 1
for both blocks is zero. Let 
and 
. So using the conservation law of linear momentum, we can write
