Instead of moving back and forth, a conical pendulum moves in a circle at constant speed as its string traces out a cone (seefigure below). One such pendulum is constructed with a string of length L- 13.9 cm and bob of mass 0.338 kg.

The Colussus is a ferris wheel at 6 Flags amusement park with a 50.4 m diameter. It rotates at 1.5 rpm. For the following, assume the rider has a mass m = 65 kg, and that the rider sits forward with feet up so the only part of the seat that exerts a force on the rider is the horizontal seat bottom. As usual, a free body diagram is a great place to start. Find the normal force exerted by a seat on a person riding the Colossus at the highest point in the ride. Hint: the speed of the rider can be computed from the circumference of their circular path and the time it takes to make one full revolution. Find the normal force exerted by a seat on a person riding the Colossus at the lowest point in the ride.
A car of mass m is negotiating a circular turn of radius R and speed v on a banked road with an angle of banking θ. The forces on the car are shown below. Ignore friction in this problem. Draw a free body of the car. Identify and show the radial direction. Pick coordinate axes with x pointing in the radial direction towards the center of the circle and y in the vertical direction. Show the coordinate axes on the free body diagram. Set up Newton’s Laws in the radial and vertical direction. Which force provides the centripetal force? Use the equations in part C to solve for the speed of the car in terms of R, Does the speed depend on the mass of the car? If R=250.0 m, m=750.0 kg, calculate the speed of the car.
