4.35 Two adults and a child want to push a wheeled cart in the di- rection marked x in Fig. P4.35 (next page). The two adults push with horizontal forces F₁ and F2 as shown. (a) Find the magnitude and direc- tion of the smallest force that the child should exert. Ignore the effects of friction. (b) If the child exerts the minimum force found in part (a), the cart accelerates at 2.0 m/s² in the +x-direction. What is the weight of the cart?
