A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinetic energy after this perfectly inelastic collision?

A. 0.0 joules

B. 3.2 * 103 joules

C. 1.0 * 104 joules

D. 1.3 * 104 joules ... ?

I think the correct answer from the choices listed above is option A. The kinetic energy after the perfectly inelastic collision would be zero Joules. A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. Hope this answers the question.
