Answer:
A). 18.84 radians per minute
B). 376.80 feet per minute
Step-by-step explanation:
As we know carousal is moving with 3 revolutions per minute.
(a). Angular speed = 3 revolutions per minute
= 3 × (2π) per minute
= 6π per minute
= 6×(3.14)
= 18.84 radians per minute
B). Since linear speed = Radius × Angular speed
=
= 20 × 18.84
= 376.80 feet per minute
