Question

Two balls have the same mass. One ball moving along the positive x axis and the other ball moving along the positive y axis undergo perfectly inelastic collision. What can you say about the motion of the balls after the collision?

A. Stick and move together
B. Separate immediately
C. First ball stops while other starts moving
D. The two balls travel off in opposite directions

Answer 1

In a completely inelastic collision, the two objects stick together after the collision.

Answer 2

Answer;

A. Stick and move together

Explanation;

• A perfect inelastic collision is a type of collision in which in which part of kinetic energy is converted to other form of energy during the collision.
• In an elastic collision on the other hand, is a type of collision in which both conservation of momentum and conservation of kinetic energy are observed.
• During perfectly inelastic collision, the objects or bodies involved stick together and move as a single object after the collision. These type of collisions result to in loss of maximum kinetic energy, which is converted into heat or in the work done in deforming the objects involved.
