You’ve taken your neighbor’s young child to thecarnival to ride the rides. She wants to ride TheRocket. Eight rocket- shaped cars hang by chains fromtheoutside edge of a large steel disk. A vertical axle throughthe center of the ride turns the disk, causing the cars to revolvein a circle. You’ve justfinished taking physics, so youdecide to figure out the speed of the cars while you wait. Youestimate that the disk is 5m in diameter and the chains are6mlong. The ride takes 10s to reach full speed, then the carsswing out until the chains are 20° from vertical. What isthe car’s speed?
