Reference no: EM13673449

A ceiling fan is rotating at 0.96 rev/s. When turned off, it slows uniformly to stop in 24 minute.

Obtain how many revolution does the fan make in this time?

Using the result from part (a), obtain the number of revolutions the fan must make for its speed to decrease from 0.96 rev/s to 0.48 rev/s.
