An amusement park ride consists of a large vertical
wheel of radius R that rotates counterclockwise on
17. The kinetic energy of the rock when it is at the
same height as point D is most nearly
a horizontal axis through its center, as shown above.
The cars on the wheel move at a constant speed v.
Points A and D represent the position of a car at
the highest and lowest point of the ride, respectively.
A person of weight F, sits upright on a seat in one
of the cars. As the seat passes point A, the seat exerts
a normal force with magnitude 0.8F, on the person.
While passing point A, the person releases a small
rock of mass m, which falls to the ground without
hitting anything.
(A) m
(B) 2mgR
(C) AmgR
