Question

Grace is playing with her dolls and decides to give them a ride on a merry-go-round. She places one of them on an old record player turntable and sets the angular speed at 33.3 rpm. What is their angular speed in rad/s

Answer 1

Answer:
`3.48\ rad/s`

Step-by-step explanation:

Given

Angular speed in rpm is 33.3 rpm

To convert it into rad/s, multiply it with
`(2\pi)/(60)`

Angular speed(rad/s)

`\Rightarrow (2\pi * 33.3)/(60)\\\\\Rightarrow 3.48\ rad/s`
