The time it takes a spinner to stop completely is 12 seconds. If the spinner completes 6 revolutions in this time, what was the average angular velocity of the spinner, in radians per second, for the 12-second interval?
Accepted Solution
A:
The angular velocity by definition is given by: w = rev / t Where: rev: revolutions t: time Substituting values we have: w = (6 * (2 * pi)) / (12) w = 3.141592654 rad / s Answer: the average angular velocity of the spinner, in radians per second, for the 12-second interval is: w = 3.141592654 rad / s
