Problem 7CQ

A number of amusement parks have rides that make vertical loops like the one shown in Figure 6.33. For safety, the cars are attached to the rails in such a way that they cannot fall off. If the car goes over the top at just the right speed, gravity alone will supply the centripetal force. What other force acts and what is its direction if: (a) The car goes over the top at faster than this speed? (b)The car goes over the top at slower than this speed?

Step-by-Step Solution:

Solution 7CQ Step-by-step solution Step 1 of 3 When a car goes in a vertical loop, the two forces acting on the car in this case are its weight (W) and the normal force of the car (N) .When the car is on the top of the vertical loop, these two forces must add up to give a net external centripetal force that pushes you forwards and counteracts the centripetal force acting towards the centre and thus the car doesn’t fall off the rails. Also, an inertial force acts on the passengers that press the body of the passengers to the outside of the loop as the car spins around. Step 2 of 3 (a) When the car goes over the top at faster than this speed, then the centripetal force will be greater than the gravitational force and so the car will tend to fall towards the centre.
