Calculate the displacement at the end of 20 seconds.
To calculate the displacement at the end of 20 seconds using the velocity-time graph, we need to find the area under the graph within the time interval of interest.
Given that the graph is a straight line with a constant velocity of 10 m/s for the first 10 seconds, we can calculate the area of the rectangle formed. The width of the rectangle is 10 seconds, and the height is 10 m/s.
Area of the rectangle = width x height = 10 seconds x 10 m/s = 100 m
Therefore, the displacement at the end of 20 seconds is 100 meters.
