A) How high can a car coast up (engine disengaged) if friction is negligible and its inital speed is 96.0 km/h?
B) If, in actuality, a 750 kg car with an initial speed of 96.0 km/h is observed to coast up a hill to a height of 17.0 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 of 2.5 degrees above the horizontal.
