The problem is:(adsbygoogle = window.adsbygoogle || []).push({});

The angular speed of a propellor on a boat increases with constant acceleration from 50 rev/min to 150rev/min in 2.5s.What is the angular acceleration of the propellor?

I'm not sure how to go about the problem.So far I've converted the 50rev/min and the 150rev/min to rad/s.Do I have to work out wf-wi and tf-ti or am I going about it wrong?

Thanks!
