A roller-coaster car of mass 330 kg (including passengers) travels around a horizontal curve of radius 44.7 m. Its speed is 10.0 m/s. A) What is the direction of the total force exerted on the car by the track? Enter a positive angle if the direction is above horizontal and a negative answer if the direction is below horizontal. in degrees B) If the track is frictionless, then what banking angle would ensure that the car does not slide off of the track? (The banking angle is the angle between the direction normal to the track and the vertical.) in degrees
