Answer:

if u think that my answer is correct then follow me and mark me as brainliest

Explanation:

In this case, the initial angular velocity of the fan is ω

0

=0 and the final angular velocity of the fan is ω=100rev/sec.

The total number of revolutions before the fan coming to stop is calculated as follows.

θ=(

2

ω+ω

0

)t=(

2

100+0

)×(5×60)=15,000rev

Hence, the total number of revolution made before it stops is 15,000rev.
