In a lab investigation, one group of students (group A) measures the speed of a 0.1kg car at 2.5m/s at the bottom of a hill. Another group of students (group B) measures the speed of the car at 3m/s at the bottom of the hill. Both cars started at the top of a hill that is 1m high. Calculate the potential and kinetic energies for each group's car.
