An automobile having a mass of 1100 kg initially moves along a level highway at 110 km/h relative to the highway. It then climbs a hill whose crest is 40 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill.
Let g = 9.81 m/s2.
For the automobile, determine its change in kinetic energy and its change in potential energy, both in kJ.
