At the bottom of the hill, group A measures the speed of a 0.17-kg car at 3.85 m/s while group B measures the speed of the same car at 4.45 m/s. The position when the car is started to move from the top of the hill is 3 m. a). Calculate the potential energy of the car before its speed is measured. b.) Calculate the kinetic energy of the car for group A. c.) Calculate the kinetic energy of the car for group B. [2] d. How much is the energy lost due to friction for the car that is measured by group A and B?
