AP Physics Question An amusement park ride consists of a large vertical wheel of radius that rotates counterclockwise on a horizontal
axis through its center, as shown above. The cars on the wheel move at a constant speed . Points and
represent the position of a car at the highest and lowest point of the ride, respectively. A person of weight sits
upright on a seat in one of the cars. As the seat passes point , the seat exerts a normal force with magnitude
on the person. While passing point , the person releases a small rock of mass , which falls to the ground
without hitting anything.

2. Which of the following best describes the passenger’s linear and angular velocity while passing point ?

A

Constant Changing

B
Linear Velocity Angular Velocity

C
Linear Velocity Angular Velocity
Changing Changing

D
