Yes.
Elastic collision: objects bound against each other after the collision. - One is moving and the other is at rest. - Both objects are moving. Inelastic collision: objects stick together after the collision. - One is moving and the other is at rest. - Both objects are moving.
Yes. For example, if both are at rest, both have zero momentum - but that's not the only case.
Amplitudethe maximum distance the particles of the medium carrying the wave move away from their rest position
No, two cars traveling at the same speed will not come to rest at the point of impact in a frontal collision. The impact will cause both cars to decelerate rapidly, but they will continue to move forward after the collision due to the conservation of momentum. The final resting positions will depend on the specific details of the collision.
Light 'particles' (photons) have no rest mass.

I won't do all the algebra but here's the setup; Both momentum and kinetic energy are conserved in an elastic collision so you set the known momentum of puck 1, before the collision equal to the sum of the unknown momentum's of puck1 & puck2 after the collision. You then set the known kinetic energy of puck1 before collision to the sum of the kinetic energies of puck1 & puck2 after the collision. This gives you two equations in the unknown velocities after the collision. Solve for one velocity from the momentum equation, square it and substitute it in the KE equation. This will give you a quadratic equation in one unknown velocity. Solve for the two possible solutions. Try each solution back in the original momentum equation. One solution will give a non physical result so you discard it and use the one that gives you a physically possible solution. One possible nonphysical result is if puck2 remains at rest and puck1 continues East (positive velocity). I chose East as positive for convienence. So if an unknown velocity comes out negative it means its moving West.

A wave's ___________ is a measure of how far the particles in a medium move away from their normal rest position.
Yes.
Potential energy is when the particles are at rest and kinetic energy is when the particles are in motion.

True
it is possible but it is not fun for the rest of the room.
