Hi, I do not know why my answer is wrong.

(a) How high (in m) a hill can a car coast up (engine disengaged} if friction is negligible and its initial speed is 100 kmjh? (Enter a number.) 393274683212 J m (b) If, in actuality, a 750 kg car with an initial speed of 100 kmfh is observed to coast up a hill to a height 17.0 n1 above its starting point, how much thermal energy (in J) was generated by friction? [Enter a number.) 454916175456 x J (c) What is the average force of friction (down the Slope) if the hill has a slope 2.5U above the horizontal? [Enter your answer in N. Enter a number.) 16014 9799712 x N
