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