SUMMARY
A coin with a diameter of 2.20 cm, initially spinning at 15.9 rad/s, rolls on a horizontal surface until it stops due to an angular acceleration of 1.76 rad/s². By applying the formula omega(t) = omega(0) + alpha*t, the time taken for the coin to come to rest can be calculated by setting the final angular velocity to zero. This discussion emphasizes the relationship between angular motion and linear distance traveled before stopping, providing a clear method for determining the distance rolled.
