Asked by marie
A small ball of mass 2.00 kilograms is moving at a velocity 1.50 meters/second. It hits a larger, stationary ball of mass 5.00 kilograms. What is the kinetic energy of the system after the collision if the collision is elastic?

if energy is conserved, KE after=KE before
KE after=1/2 m v^2=.001 *1.5^2 Joules
KE after=1/2 m v^2=.001 *1.5^2 Joules
