A woman pulls a sled which, together with its load, has a mass of m kg. If her arm makes an angle of θ with her body (assumed vertical) and the coefficient of friction (a positive constant) is μ , the least force, F , she must exert to move the sled is given by F = m g μ sin θ + μ cos θ . If μ = 0 . 15, find the maximum and minimum values of F for 0 ≤ θ ≤ π / 2. Give answers as multiples of mg .
