Part G Assume that friction causes the car to lose 37,800 joules of energy as it travels from the top of the first hill to the bottom. What's the car's velocity at the bottom of the first hill? Use your answer from part C (416,500) and the formula v= to determine the answer.

(This formula is the kinetic energy formula, rearranged to find v.) 2KE​
