Copyright © by Holt, Rinehart and Winston. All rights reserved. Sample Problem Kinetic Energy in Perfectly Inelastic Collisions Two clay balls collide head-on in a perfectly inelastic collision. The first ball has a mass of 0.500 kg and an initial velocity of 4.00 m/s to the right. The second ball has a mass of 0.250 kg and an initial velocity of 3.00 m/s to the left.What is the decrease in kinetic energy during the collision? 1. Define Given: m 1 = 0.500 kg m 2 = 0.250 kg v 1,i = 4.00 m/s to the right, v 1,i = +4.00 m/s v 2,i = 3.00 m/s to the left, v 2,i = –3.00 m/s Unknown: KE = ?
