[SOLVED] Centrifuge Revolutions?

1. The problem statement, all variables and given/known data

A centrifuge accelerate from rest to 15,000 rpm in 240s. Through how many revolutions did it turn in this time?

2. Relevant equations

am i approaching this problem correctly?

3. The attempt at a solution

15000rev/m (1m/60s) (240s) = 60000 rev

It is accelerating though. What you have calculated is for a constant angular velocity. What is the definition of angular acceleration? If you know that equation you can solve this problem. Don't forget to convert into radians where necessary.
