What is the direction of the force exerted by the car on the passenger as the car goes over the top of the amusement ride pictured in Figure 6.33 under the following circumstances: (a) The car goes over the top at such a speed that the gravitational force is the only force acting? (b) The car goes over the top faster than this speed? (c) The car goes over the top slower than this speed?
Solution 8CQ Step-by-step solution Step 1 of 4 As an observer inside the system a) If the speed of the car is the right speed which makes the weight equal to the centrifugal force. The normal force from the rails is zero. In this case the weight of the objects is centripetal force. Step 2 of 4 (b) If the car goes faster than the right speed. The centrifugal force is bigger than the weight. The centrifugal force compresses the passenger towards the rails. Normal force and the weight towards the center of the rail.
