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: $3.48\ rad/s$

Explanation:

Given

Angular speed in rpm is 33.3 rpm

To convert it into rad/s, multiply it with $\frac{2\pi}{60}$

Angular speed(rad/s)

$\Rightarrow \dfrac{2\pi \times 33.3}{60}\\\\\Rightarrow 3.48\ rad/s$
