Question

1. a baseball hits a bat and both move in opposite directions after the collision. what type of collision is it?

Explanation:

In an in - elastic collision, objects stick together or deform significantly. In an elastic collision, kinetic energy and momentum are conserved and objects bounce off each other. When a baseball hits a bat and they move in opposite directions, kinetic energy and momentum are conserved. So it's an elastic collision.

Answer:

Elastic collision
