Answer:
Explanation:
The angle in rotational motion is given by:
Recall that the angular speed is larger than regular frequency (in rpm) by a factor of , so:
The wheel spins from rest, that means that its initial angular speed is zero(). Finally, we have to convert the given time to minutes and replace in the first equation:
