Blocks A and B are held on the palm of your outstretched hand as you lift them straight up at constant speed. Assume mB>mA and that mhand=0. a. Draw separated free-body diagrams for A, B and your hand. Show all vertical forces and make sure the vector lengths indicate the relative sizes of the forces. b. Rank in order from largest to smallest all of the vertical forces. Explain your reasoning. Now the hand is lifting the blocks so they have an upward acceleration. c. Draw separated free-body diagrams for A, B and your hand. Show all vertical forces and make sure the vector lengths indicate the relative sizes of the forces. d. Rank in order from largest to smallest all of the vertical forces for when the block is accelerating. Explain your reasoning.
