...slows uniformly to a stop in 14 s.  (a) How many revolutions does it make in this time?  (b) Using the result from part (a), find the number of revolutions the fan must make for its speed to decrease from 0.70 rev/s to 0.35 rev/s.

a. 14 s * 0.70 rev /s

= 9.8 rev

b  since the speeds slows uniformly, then to stop half the speed will take half the time and cover half the number of revolutions

= 4.9 rev
