mass of person, m = 980/9.8 = 100 kg
velocity of car, v = 40* 5 / 18 = 11.111 m/s
kE = 0.5 m v^2 = 0.5 * 100* 11.11^2 = 6172.84 J

1a) What is the kinetic energy (in J) of a 2610-pound automobile traveling at 62.5 km per hour? b) What energy transformations take place when a moving car brakes and skids to a stop? Select all that apply. Total energy is conserved. The kinetic energy of the car is converted into thermal energy. The brakes and tires are cooler after the car stops then just before the brakes were applied. Total energy is not conserved.

A 1200 kg car traveling at 60 mph quickly brakes to a halt. The kinetic energy of the car is converted to thermal energy of the disk brakes. The brake disks (one per wheel) are iron disks with a mass of 4.0 kg. Estimate the temperature rise in each disk as the car stops. Express your answer using two significant figures.
