Question:
A car loses contact with the road if it goes over the top of a hill too fast. Imagine a semi- circular hill with a radius of 12 m.
(a) Draw a free body diagram (FBD) of a car going over the very top of the hill. You may assume that rolling friction is negligible.
(b) Which force goes to zero as the car loses contact with the road?
(c) Solve for the maximum speed the car can be going before it loses contact with the road.
(d) Repeat the problem, but for the minimum speed for a roller coaster cart inside a loop- the-loop with the same radius.
