Problem 8.42
You've taken your neighbor's young child to the
carnival to ride the rides. She wants to ride The
Rocket. Eight rocket-shaped cars hang by chains
from the outside edge of a large steel disk. A
vertical axle through the center of the ride turns the
disk, causing the cars to revolve in a circle. You've
just finished taking physics, so you decide to figure
out the speed of the cars while you wait. You
estimate that the disk is 6 m in diameter and the
chains are 6 m long. The ride takes 10 s to reach
full spee then the cars swing out until the chains
are 20° from vertical.

V =
