25. A new amusement park ride is shown in the diagram. 10 m C The mass of the small car, including its contents, is 400 kg. and the radius of the loop is 10 m. Assume that the track is frictionless and that no mechanism holds the car in contact with the track. (a) In order that the car stay on the track at B, what minimum velocity must it have at that point? (b) From what minimum height, h, must the car start from rest in order to do this? () is the mass of the car a factor in determining k? Explain.
