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
Linear Velocity Angular Velocity
Constant Changing

B
Linear Velocity Angular Velocity
Constant Constant

C
Linear Velocity Angular Velocity
Changing Changing

D
Linear Velocity Angular Velocity
Changing Constant

The linear velocity is changing and the angular velocity is Constant best describes the passenger’s linear and angular velocity while passing a point.

The rate of change of angular displacement is defined as angular speed, and it is stated as follows:

ω = θ t

Where,

θ is the angle of rotation,

t is the time

ω is the angular velocity

The linear velocity is given as the product of angular velocity and radius.

v=ωr

In the circular motion, the linear velocity is changing. Because the radius is changing.While the angular velocity is constant.Because it is an independent quantity.

Hence the Linear velocity is changing and the angular velocity is Constant best describing the passenger’s linear and angular velocity while passing a point.
