3. A drawing of a strobe photograph that shows the position of two balls at eight different times as the balls move to the right is shown below. The strobe flashes once per second, and the first flash is at time zero. Each ball travels the same total distance. Ball A Ball B (a) In the space below, graph the position of the two balls as a function of time. Be sure to label your graph so that it is clear which ball each line you draw represents. Position 7 8 Time, sec (b) In the space below, graph the velocity of the two balls as a function of time. Again label your graph so that it is clear which line you draw belongs to which ball. Velocity 8 Time, sec (c) At what time or times, if any, do the balls have the same position
