Chapter 6, Problem 7(choose chapter or problem)
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?

ANSWER:Q:A number of amusement parks have rides that make vertical loops like the one shown inFigure 6.33. For safety, the cars are attached to the rails in such a way that they cannot falloff. If the car goes over the top at just the right speed, gravity alone will supply thecentripetal force. What other force acts and what is its direction if: (a) The car goes overthe top at faster than this speed (b)The car goes over the top at slower than this speed SolutionStep 1 az:The diagram shows a type of roller coaster ride in which the radius in the bottom part is morethan that of the top section. There are two main forces acting in this scenario (1) Gravitationalforce (2) The normal force.When the ride is at the top, the gravitational force acts as the centripetal force and is directedtowards inwards the circular loop, Since the track is at the top of the ride, the normal force is alsodirected downwards. When the ride is at the bottom, the gravitational force is directed towards the ground and thenormal force directed upwards.
