Ответ:
t = 9.25 s
Explanation:
Given that,
Initial angular velocity,
(at rest)
Final angular velocity,
Angular acceleration,
We need to find the time it take the wheel to come up to operating speed. We know that the angular acceleration in terms of angular speed is given by :
So, it will reach up to the operating speed in 9.25 s.
