A car and atruck are heading directly toward one another on a straight and narrow street, but they avoid a head-on collision by simultaneouslyapplying their brakes at t = 0. The resulting velocity-versus-time graphs are shown in Figure 31 What is the separation between the car and the truck when they have come to rest, given that at t = 0 the car is at x = 15 m and the truck is at x = –35 m? (Note that this information determines which line in the graph corresponds to which vehicle.)
