Question:

(a)How high (in m) a hill can a car coast up (engine disengaged) if friction is negligible and its initial speed is 86.0 km/h?

(b)If, in actuality, a 750 kg car with an initial speed of 86.0 km/h is observed to coast up a hill to a height 14.0 m above its starting point, how much thermal energy (in J) was generated by friction?

(c)What is the average force of friction (down the slope) if the hill has a slope 2.5 above the horizontal?
