Problem
A 0.40kg ball travels in a straight line at 4.0m⋅s−1 and collides with a 0.20kg ball moving in the same direction at 1.0m⋅s−1. After the collision, the two balls join together and continue along the original line of motion. Approximately what percentage of the initial kinetic energy of the system is dissipated?
(a) 45\%
(b) 18\%
(c) 6\%
(d) 64\%
