Solve the problem.
-A turntable rotates at 61 revolutions per minute. What is its angular speed in radians per second?
A) $\frac { 61 } { 60 } \pi$ radians/second
B) $\frac { 61 } { 30 } \pi$ radians/second
C) $\frac { 60 } { 61 } \pi$ radians/second
D) $\frac { 30 } { 61 } \pi$ radians/second

Question

Quizplus · Accepted Answer

The angular speed in radians per second is found by converting revolutions per minute to radians per second. Since there are $2\pi$ radians in a revolution and 60 seconds in a minute, the conversion is $61 \times \frac{2\pi}{60} = \frac{61}{30}\pi$ radians/second.
