1. The diagram to the right is a section of roller coaster at an amusement park. The mass of the car and the riders is 110kg and the motion of the car on the track can be considered frictionless. At point A, the car is 5m above the lowest point on the track (point B) and is moving at 8.5m/s. (a) How fast is the car moving at point B? (b) The car just barely makes it over point C, effectively with a speed of Om/s. How high is point C above point B? (8) 5.0 m
