Answer the following problems

11.16 .. Suppose that you can Figure E11.16 lift no more than 650 N (around 150 lb) unaided. (a) How much 1.4 m can you lift using a 1.4-m-long wheelbarrow that weighs 80.0 N and whose center of gravity is 0.50 m from the center of the 1 0.50 m wheel (Fig. E11.16)? The cen- ter of gravity of the load car- ried in the wheelbarrow is also 0.50 m from the center of the wheel. (b) Where does the force come from to enable you to lift more than 650 N using the wheelbarrow
