A coin with a diameter of2.64 cm isdropped onto a horizontal surface. The coin starts out with aninitial angular speed of 28.1 rad/s and rolls in a straight linewithout slipping. If the rotation slows with an angulardeceleration of magnitude 1.12 rad/s2,
How far does the coin roll before coming to rest?
