3. You push a grocery cart along a level floor in the presence of friction effects between the cart and the floor. a. Draw force diagrams for you, the cart, and the floor/earth. Fully label all vectors. b. While you are making the cart speed up, how does the size of the force you apply on the cart b. compare to the size of the force the cart exerts on you? Explain. c. While you are making the cart speed up, how does the size of the frictional force on the cart by the floor compare to the frictional force on you by the floor?
