Asked by Sam
A pool ball of mass 100g and velocity [5,-4]m/s collides with a stationary pool ball of the same mass. After the collision, the pool balls have velocites [2,-3]m/s and [3,-1]m/s. Is the collision elastic? Explain your answer.

Lets check energy
before: 1/2 .1 * (25+16)=
2.05 joules
after= 1/2 .1*(4+9)+1/2 .1(9+1)
=1/2 (1.3)+1/2 (1)=1/2 (2.3) not elastic. Energy is lost
