a car with a mass of 1800 kg and a speed of 25 m/sec brakes to a stop. how many calories of heat are generated by the brakes as a result?
Added by Jennifer J.
Step 1
5 * mass * speed^2 Given mass = 1800 kg and speed = 25 m/s KE = 0.5 * 1800 * 25^2 KE = 0.5 * 1800 * 625 KE = 562500 J Show more…

Someone is driving a car at speed 100 miles per hour, and then applies the brakes to bring the car to a stop. How many calories of heat are produced in the stopping process if the car mass is 1000 kg? (Assume that all of work done becomes heat.)

A 1000 kg car, traveling at 30 m/s, is brought to a complete stop by applying the brakes. If all of the kinetic energy of the car is converted to heat in the brakes, about how much heat in kcal is generated?
