25. (a) how high a hill can a car coast up (engine disengaged) if work done by friction is negligible and its initial speed is 110 km/h? (b) if, in actuality, a 750-kg car with an initial speed of 110 km/h is observed to coast up a hill to a height 22.0 m above its starting point, how much thermal energy was generated by friction? (c) what is the average force of friction if the hill has a slope 2.5º size 12{2 "." 5°} {} above the horizontal?
