Answer:
The change in momentum of the tennis ball can be represented graphically using a momentum-time graph. In this case, since we are dealing with horizontal motion, the x-axis represents time, and the y-axis represents momentum.
1. Start the graph at the initial momentum of 5 kg·m/s.
2. Draw a line decreasing to 0 kg·m/s, indicating the collision with the wall.
3. After the collision, draw a line going in the opposite direction, starting from 0 kg·m/s and reaching a momentum of 4 kg·m/s.
This graphical representation shows the initial momentum, the decrease to 0 during the collision, and the increase in the opposite direction after the bounce. The area under the graph represents the impulse applied to the ball, which is the change in momentum.
