2. Write a brief explanation of what the graph shows. Point out regions

".s.. of acceleration and of relatively constant velocity.

3. Plot the total displacement of the cart against the corresponding time

in ticks using the values in Table 5-1. Use the same scale on the time

axis as you used for the graph in Question 1.

4. Write a brief explanation of the meaning of the graph. Explain any

change in the slope of the line of the graph.

5. Explain how the shape of your second graph correlates with your first

graph.

Extension

1. The first graph you plotted is called a velocity-time graph. However,

other information can be obtained from such a graph.

a. What does the area under the line of the graph represent?

b. Write an equation to represent the area under the line during the

period of uniform acceleration.

c. What does the slope of the line represent?

d. Calculate the slope of the line.
