A new park attraction consists of a vertical wheel of radius R, spinning at constant angular velocity, with cars for passengers. The passengers feel weightless at the top of the wheel. Assume that the typical mass of a passenger is m.
a) What is the magnitude of the force exerted on a passenger by the car at the top of the wheel?
b) What is the speed of the car?
c) What is the magnitude of the force exerted on a passenger by the car at the bottom of the wheel?
d) What is the magnitude of the force exerted on a passenger by the car when they are 90° from the bottom, going up?
Write your results in terms of R, m, and g. Check the units/dimensions for each answer.
