A graph of titled velocity versus time with time in seconds on the x axis numbered 0 to 10 and velocity in meters per second on the y axis numbered 0 to 50. The graph has a line from the origin to (1, 30) labeled A, a line from (1, 30) to (3, 30) labeled B, a line from (5, 40) to (6, 10) labeled C, a line from (6, 10) to (7, 10) labeled D and a line from (9,40) to (10, 20) labeled E.
The velocity of a 1.3 kg remote-controlled car is plotted on the graph.
The work of segment A is J.
