B3-WWT34: VELOCITY-TIME GRAPHS-NET FORCE Graphs are shown of the velocity versus time for two identical train engines on a straight track. A positive velocity indicates that the engine was traveling east. The scales on both axes are the same for the graphs. On each graph a point is marked with a dot. A Velocity Velocity Time Time A student comparing the net force acting on the engine at the identified points in graphs A and B states: "I think that B has the larger net force since the net force on A at the identified point is zero. What, if anything, is wrong with this statement? If something is wrong, identify it, and explain how to correct it. If the statement is correct, explain why.
