A coin with a diameter of 1.80 cm is dropped onto a horizontal surface. The coin starts out with an initial angular speed of 17.6 rad/s and rolls in a straight line without slipping. If the rotation slows with an angular acceleration of magnitude 1.72 rad/s2, how far does the coin roll before coming to rest?
