A1500-kg car travels on a level road at 42 m/s (state 1). it then continues down a hill to a lower part of the road (state 2), dropping in elevation by 25 meters in the process. if the car coasts without friction, what is its speed in state 2? assume that g = 9.81 m/s2.now imagine it coasts, starting at 42 m/s in state 1, but there is friction from aerodynamic drag and rolling resistance. the car’s speed in state 2 is now 43 m/s. if the car’s temperature stays constant, what is the heat transfer to the surrounding air?
