Answer:
200 revolutions per minute = 20.9 rad/s
Explanation:
It is given that, a figure skater is rotating at a rate of 200 revolutions per minute. It is the angular velocity of the skater. We have to convert it into radian/second.
Revolution per minute can be converted to radian per minute as :
Since, 1 radian/second = 60/2π revolutions per minute
So, 1 revolution/minute = 2π/60 radian/second
200 revolution/minute = 200 × 2π/60 radian/second
200 revolution/minute = 20.9 radian/second
Hence, this is the required solution.
