A model roller coaster car weighing 300 Kg is accelerated with a constant force F between points A and B over a period of 1.5 seconds. When the car gets to point C, the normal force exerted by the track on the car is in the downward direction and equal in magnitude to the weight of the car. (i) Determine the magnitude of F. (ii) determine the maximum height reached by the car on the upward slope. The radius of curvature of the loop is 10 m. Neglect friction losses.
