How many revolutions did the fish make?

[QUOTE="Charlene, post: 5507195, member: 595638"] [h2]Homework Statement [/h2] A fish starts at rest and uniformly accelerates. After 10 seconds, he is swimming around a rock at a rate of 3.14 rad/sec. a.) What's the magnitude of angular acceleration? b.) How many times did the fish circle the rock (how many revolutions?) [h2]Homework Equations[/h2] a.) wf=wi+alpha*t [h2]The Attempt at a Solution[/h2] a.)wf=wi+alpha*t alpha=(wf-wi)/t alpha=(3.14rad/sec-0)/10sec therefore, angular accelerate = .314 rad/sec^2 b.) .314rad/sec^2 *1rev/2pi rad = 0.50 revolutions around the rock. I just wanted to double check that i did part b correctly because i guess I'm having trouble seeing how the sec^2 on the bottom of the units end up disappearing to become just revolutions. [/QUOTE]
