    Inelastic collisions, springs and ramps

    Also, I found that in a situation like this, with inelastic collision, energy is not conserved, but momentum is.

    Inelastic collisions, springs and ramps

    Thanks for replying! The PE grav would be 4(mgy) because of the combined weight, but this is the PE at the highest point. This is where it's 100% PE and 0 KE. Since KE is 1/2mv2, the mass would be 4m, the velocity would be 1/4m?as it starts to go up the ramp, the KE falls, and the PE grows...

    Inelastic collisions, springs and ramps

    Homework Statement A block of mass M is compressed a distance x against a spring which has a spring constant k. When released, the block slides along a frictionless surface until it undergoes a completely inelastic collision with a block of mass 3M. The two blocks travel together some distance...
