On a frictionless horizontal air table, puck A (with mass 0.251 kg ) is moving toward puck B (with mass 0.374 kg ), which is initially at rest. After the collision, puck A has velocity 0.116 m/s to the left, and puck B has velocity 0.652 m/s to the right.

Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.

Solutions

Expert Solution

To solve the exercise, we will first determine the initial velocity on disk A (). We will use the following equation:

where

since is zero, the equation is as follows

Solving the above equation for

Now we determine the change of kinetic energy

For puck A

For puck B
