NettetVIDEO ANSWER:7.53. So we'll have. We have a car that's moving at 95 kilometers per hour and its mass is 1300 kilograms. We want to know how much work we have to do to stop it. So the work is going to be the change in kinetic energy. So the final kinetic energy is going to be zero if it stopped. So the amount of work we have to do is equal to its … NettetHow much work must be done to stop a 925 - kg car traveling at 95 km / h? 2.
