A centrifuge accelerates uniformly from rest to 15,000 rpm in 220 s. Through how many revolutions did it turn in this time?
BUT check my maths!
We can say that:
[1 revolution is
and 1 min=60 s]
In our case the object changes ANGULAR velocity and goes from
This corresponds to an angular acceleration:
Let us use a (rotational) kinematic relationship to find tha ANGULAR distance
But each revolution corresponds to
