counterclockwise direction.? After fixing a flat tire on a bicycle you give the wheel a spin in the counterclockwise direction.
(a) If its initial angular velocity was (+5.10 rad/s k) and it rotated an angular displacement of (+15.4 revolutions k) before friction in the pivot brought it to rest, what was its angular acceleration? You may assume it was nearly constant.
____ rad/s2 k
(Is this counterclockwise or clockwise from your vantage point? The same direction or opposite the angular velocity?)
(b) How long did the wheel rotate?
____ s
