17. A rollercoaster toy car starts from rest at position S. The section SA is frictionless. The car loses energy way up from A to B. a) What is velocity of car at A? b) How hard car pushes at point A as it starts to go up? c) The has a minimum speed just sufficient to pass the point B. How much energy car loses its way from A to B? (Find velocity at B, then find energy loss) Answer: (a) (192) m/s (b) 105.8 N (c) 735 J 20m B 2m 5836 A 17.
