Help with these questions please
At what minimum speed must a roller coaster be traveling when upside down at the top of a circle if the passengers are not to fall out? Assume a radius of curvature of 8.6.
2. A 1000kg sports car moving at 20m/s crosses the rounded top of a hill(radius = 100m). Determine (a) the normal force on the car, (b) the normal force on the 70kg driver, and (c) the car speed at which the normal force equals zero.
Thanks
