# How to get angular acceleration from spin count and angular velocity [closed]

It would be very good if someone explained me how do you get to the final answer which is already know (3.2 rad/s^2)

Have been given: ω = 20 = angular velocity (rad/s) N = 10 full spins Need to find: α = angular acceleration (rad/s^2)

Problem: Evenly accelerationg wheel gets 20 rad / s After N = 10 spins from beginning of the movement. Calculate the angular acceleration of the wheel.

Thank you.

 Hi enflam3, and welcome to Physics Stack Exchange! This is not a homework help site, so as the FAQ says, questions that just ask for the answer or method for a homework problem are not appropriate here. If you edit your question to ask about the specific concept that's giving you trouble, then it might be okay and in that case I'd be happy to reopen it. – David Zaslavsky♦ Feb 7 '12 at 21:47
