Question

1 PHYSICS QUESTION, PLEASE HELP!!! In which case is a collision between two objects completely inelastic?

The two objects bounce off each other at the same speed as before
The sum of the velocities of the two objects is the same speed before and after
The two objects stick together
The two objects leave at +30 degrees and -30 degrees from the original direction

Answer 1

Correct option C. "The two objects stick together"

Step-by-step explanation:

There are two types of collision. First one is elastic collision and other one is inelastic.

In inelastic collision, the linear momentum before and after the collision is same but the kinetic energy after the collision is not constant. It is used in the form of heat, light etc.

For an inelastic collision, two objects after collision sticks together and move with a common speed. It is one of the important factor for inelastic collision.
