Problem 63PE Construct the displacement graph for the subway shuttle train as shown in Figure 2.18(a). Your graph should show the position of the train, in kilometers, from t = 0 to 20 s. You will need to use the information on acceleration and velocity given in the examples for this figure.Figure 2.18(a): Step-by-Step Solution:

Step 1 of 6:

The distance made by the train is known as the displacement of the train. The subway shuttle train which is initially at rest starts accelerating and travels for 20 s. We are going to plot its position vs time graph for the time interval between 0 and 20 s.

The initial speed of the train The acceleration for first 20 s The initial displacement or Step 2 of 6:

The position of the train at any time is expressed as At Substituting the values in (1)  Step 3 of 6:

At   Step 4 of 6
