Aloaded grocery cart is rolling across a parking lot in a strong wind. you apply a constant force \vec{f} =(33 n)\hat{i} - (41 n)\hat{j} to the cart as it undergoes a displacement \vec{s} = (-9.4 m)\hat{i} - (3.1 m)\hat{j}.

part a
how much work does the force you apply do on the grocery cart?
express your answer using two significant figures.
