In the elastic collisions from our lab, the 2 carts bounced off each other and went in the other direction

In the inelastic collisions from our lab, the 2 carts did NOT bounce off each other, they stuck together and went in the same direction

With elastic collisions, kinetic energy is conserved. With inelastic, kinetic energy is not conserved (some is lost)
8
Elastic
Like 2 pool (billiard) balls colliding, they bounce off each other.

If we kick a soccer ball perfectly straight on, it will go far.
This would be perfectly (or as close to perfect as possible) ELASTIC
11
If we kind of miss a little and not kick the ball perfectly, it won't go as far
This would be INELASTIC, which is what most collisions are like.

Inelastic
Like 2 cars crashing into eachother, they do NOT bounce (I hope) and a lot of kinetic energy is lost to sound and heat.

Why are collisions inelastic at all? Because of the things colliding.
A rubber band bounces back to its original position when stretched (elastic). A car does NOT bounce back.

Remember the car going 15 m/s is in the opposite direction, so V2i = -15
