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 22250g00011(1500 kg)(10.0 m/s)(1500 kg)(9.8 m/s )(10 m)2.22 10 JKUmvmgy+=+=+=×The car increases its height to 15 m at the gas station.
