Problem
A runner of mass m accelerates along a horizontal track where the coefficient of static friction between the shoes and the ground is μs.
(i) Derive an expression for the maximum possible forward acceleration of the runner in terms of μs and g.
(ii) If μs=0.30, calculate the numerical value of this maximum acceleration.
