A girl, moving at 8 m/s on in-line skates, is overtaking a boy moving at 5 m/s as they both skate on a straight path. The boy losses a ball backward toward the girl, giving it speed 12 m/s relative to him. What is the speed of the ball relative to the girl, who catches it? (a) (8 + 5 + 12) m/s (b) (8 - 5 - 12) m/s (c) (8 + 5 - 12) m/s (d) (8 5 + 12) m/s (e) (8 + 5 + 12) m/s
You push a 80-kg file cabinet to the right on a frictionless horizontal surface with a force of 175 N from rest, the cabinet moves a distance of 12 m. What is the final speed of the cabinet, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
2) A classical cartoon situation: Lobster, with mass m, on one edge of a carpet with length L and mass M is suddenly starting to run at maximum speed Vmax along the carpet. Because there is negligible friction between the carpet and the floor, the carpet slides out underneath Lobster, and so it doesn't quite move as much as it wished. a. Make a detailed schematic drawing of the situation. b. How long until Lobster reaches the end of the carpet? c. Watching it from a steady frame of reference, how fast and in which directions are the carpet and Lobster moving, respectively? d. How far did Lobster progress in that steady frame of reference when it reaches the end of the carpet? e. If m = 1 kg, M = 3 kg, L = 20 m, Vmax = 0.25 m/s, how long until Lobster reaches the end of the carpet, and how far has it moved in the steady frame of reference? How far has it moved on the carpet?
