A rotating wheel requires 3.00s to rotate 37.0 revolutions. Its angular velocity at the end of the 3.00-s interval is 98.0rad/s. What is the constant angular acceleration of the wheel?(adsbygoogle = window.adsbygoogle || []).push({});

What i did was i used average w=delta(theta)/delta time. Then i used average w=radical(w^2+wo^2) to find wo. Then i plugged it all into w=wo+alpha(t) and i got alpha=12.67. The answer is suppose to be 13.7rad/s^2. Can someone help me on this problem?

thanks
