(a)
Find the angular speed of the carousel .
(a)
Answer to Problem 65E
The angular speed of the carousel is 25.133 radians per minute
Explanation of Solution
Consider,
So
Each revolution generates 2p radians. It follows that in 4 turns, a carousel turns
Angular speed is,
=25.133 radians per minute
Hence the angular speed of the carousel is 25.133 radians per minute
(b)

Explanation of Solution
Given:
Consider,
So
Each revolution generates 2p radians. It follows that in 4 turns, a carousel turns
The linear speed is,
Hence the linear speed of the carousel is 628.32 foot per minute
