acceleration=(wf-wi)/time
= 2PI(.485-1.65)/12.2
displacement (radian)=avgspeed*time
= 2PI(wf+wi)/2 * 12.2
A spinning wheel steadily slows from an initial angular velocity of 1.65 rev/s to 0.485 rev/s in 12.2 s.
(a) Calculate the wheel's angular acceleration in radians per second squared.
rad/s2
(b) What angle does it go through during that time?
rad
