On blank paper (or graph paper, if you have some already out), draw a Free Body Diagram (FBD) for each object described below. Label each force. Pay attention to the lengths of your vectors. They do not need to be exactly to length (you don't have enough information!), but the relative sizes are important. 2a) A ball, just after release, on the way up. Ignore air resistance. 2b) Skier, holding onto a rope, being lowered down the hill. Consider friction. 2c) Box B, moving to the left at decreasing speed. Note: Box A is in contact with Box B, but the two boxes are not attached. Consider friction. 2c) Box B, moving to the left at decreasing speed. Note: Box A is in contact with Box B, but the two boxes are not attached. Consider friction. 2d) A woman is moving downward in an elevator at increasing speed. Draw 3 FBDS- one for the elevator, one for the woman, and one for the elevator/woman system. In the box below, describe any 3rd Law pairs that you see among the forces shown in is a 3rd force on the FBD of the your 3 FBDS for 2d. For example: The law pair to the force on the FBD of the
