A position-time graph is shown below: Position vs. Time 15 Position (cm) -> Time (seconds) -> Which statement accurately describes the motion of the object in the graph above over 10 seconds? The object moves forward at 1 cm/s, stops, and then continues at the same velocity. The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s. The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s....

3. A gun tackle consits of a light rope and two ideal pulleys. One end of the rope is attached to the ceiling and wrapped around both pulleys, as depicted, while the other end is fastned to mass A. Mass B hangs off the pulley that is free to move. The second pulley is attached to the ceiling. Initially the blocks, which have the same mass, are suspended at the same distance from the ceiling and are subsequently released...
