A car is speeding along a level road at 25 m/s. The brakes abruptly bring the500 kg car to a speed of 3 m/s over a distance of 5 m. Determine the force applied by
brakes and the work done by the car on the brakes.
Yes you can calculate the work done by calculating the change in the kinetic energy. The change in kinetic energy would simply be the difference between the Final and the initial kinetic energies. [find out yourself]
