Object A has of mass 7.20 kilograms, and object B has a mass of 5.75 kilograms. The two objects move along a straight line toward each other with velocities +2.00 meters/second and -1.30 meters/second respectively. What is the total kinetic energy of the objects after the collision, if the collision is perfectly elastic? 19.3 joules 21.9 joules 38.5 joules 43.0 joules 50.8 joules

1. Elastic collision means Kinetic Energy is conserved 2. Calculate the KE before collision 2. It wil be the same after collision
