A centrifuge accelerates uniformly from rest to 13000 rpm in 220 s. through how many revolutions did it turn in this time?

We have the following angular velocity:

w = 13000 rpm

We are going to convert to revolutions per second.

We have then:

w = 13000 * (1/60)

w = 216.6666667 rev / sec

We now multiply the angular velocity by time:

(216.6666667) * (220)

= 47666.66667 rev

Rounding:

47667 rev

Answer:

it did turn about 47667 rev in this time
