[QUOTE="phoenixation, post: 2284002, member: 797287"] ...narrow street? A car and a truck are heading directly toward one another on a straight and narrow street, but they avoid a head-on collision by simultaneously applying their brakes at t = 0. The resulting velocity-versus-time graphs are shown in the figure . 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_c = 11 m and the truck is at x_t = -39 m? Express your answer using two significant figures. d= 50. m is incorrect, so i'm not quite sure what to do because i was told to do 11 - (-39) = 50 m yet it's not correct. [/QUOTE]
