Question
a) The two systems shown are very similar. In both cases, the horizontal surface is frictionless. All the boxes have the same mass. In which system will box 2 have a larger acceleration? Are they the same? How do you know? 2 no friction The solid line represents the center-of-mass. b) Here is a graph of position vs. time for two objects (dotted line and dashed line) involved in a collision (at the star). There is a mistake in the graph! What is the mistake, and how do you know? 1 Note: I did not give you any numbers on the graph, and you don't need them to find the error! X 2 no friction 1 t

c) The graph shows potential energy vs. position. The object has a maximum kinetic energy of 1.0 J. On the same graph, draw and label the total energy (TE) and kinetic energy (KE) vs. position. Circle the turning points. d) A block is attached to a spring. It is given a push. A graph of position vs. time is shown. Draw a graph of velocity vs. time. Your graph should be drawn correctly to scale. E (J) 4 3. 2 0 0.1m 0.0m -0.1m 0.5m/s 0.0m/s -0.5m/s Xm V 1s 1s 2s 十25 2s PE -X 3s 3s 3
