A turntable rotates at 100 rev/min. Calculate the angular speed in rad/s and in degree/s.

Open in App

Solution

100 revolution/minute
one revolution = $2 π$ radius.
$\Rightarrow \frac{100 \times 2 π}{60}$ radian /second.
$\Rightarrow \frac{10}{3} π$ radian/second.
again, one revolution = 360 degree
So :- $\frac{100 \times 360}{60}$ degree/sec
= 600 degree/second

100 revolution/minuteone revolution = 2π radius. ⇒100×2π60 radian /second.⇒103π radian/second.again, one revolution = 360 degreeSo :- 100×36060 degree/sec= 600 degree/second
