Web(Because coefficients of friction are approximate, the answer is given to only two digits.) Discussion. We could also solve part (a) using the first expression in F c = m v 2 r F c = mr ω 2}, F c = m v 2 r F c = mr ω 2}, because m, m, v, v, and r r are given. The coefficient of friction found in part (b) is much smaller than is typically found between tires and roads.
