What angular acceleration is necessary to increase the angular speed of a fan blade from 8.2 rad/s to 15.5 rad/s in 5.9 s? Answer in units of rad/s 2

Explanation:

The angular acceleration () of an object under a circular motion, is the rate of change of its angular velocity () with respect to time. Therefore, angular acceleration is defined as:

Here is the final angular speed and is the initial angular speed. So, replacing the given values, we get the needed angular acceleration:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
