... 1. The greatest deceleration (of magnitude a) is provided by the maximum friction force (Eq. 6-1, with FN = mg in this case). Using Newton’s second law, we find a = fs,max /m = sg. Equation 2-16 then gives the shortest distance to stop: |x| = v2/2a = 36 m. In this calculation, it is important to f ...
