1. A woman pulls a sled which, together with its load, has a mass of m kg. If her arm makes an angle of with her body (assumed vertical) and the coefficient of friction (a positive constant) is , the least force, F, she must exert to move the sled is given byF=mgsin+cos.If =0.25, find the maximum and minimum values of F for 0/2. Your answers will involve the unspecified constants m and g.

maximum force = Newtons minimum force = Newtons
