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.
