Question 1198899: -5000 J of work is done when a 2000 kg car traveling at 5 m/s slows down. What is the KE of the car after it slows down? Answer by ikleyn(52880) (Show Source):
The initial kinetic energy (KE) was = = 25000 joules.
5000 joules was spent for slowing down.
The resting KE is the difference 25000 - 5000 = 20000 joules. ANSWER
