10.13. Model: Model the car as a particle with zero rolling friction. The sum of the kinetic and gravitational potential energy, therefore, does not change during the car’s motion. Visualize: Solve: The initial energy of the car is 22 2 5 0g 0 0 0 11 (1500 kg)(10.0 m/s) (1500 kg)(9.8 m/s )(10 m) 2.22 10 J K U mv mgy += + = + = × The car increases its height to 15 m at the gas station.
