Question

Two balls collide head-on in a perfectly inelastic collision. The first ball has a mass of 0.75 kg and an initial velocity of 5.0 m/s to the right. The second ball has a mass of 0.40 kg and an initial velocity of 3.5 m/s to the left. What is the decrease in kinetic energy during the collision?

Answer 1

Step-by-step explanation:

Momentum conservation

V=3.38

Delta kinetic energy =1/2m(vi^2-v^2)
