Cars A and B move in the same direction in adjacent lanes. The position x of car A is given in Figure, from time t = 0 to t = 7 .0 s. The figure's vertical scaling is set by xs = 32.0 m. At t = 0, cat B is at x = 0, with a velocity of 12 m/s and a negative constant acceleration as.(a) What must a6be such that the cars are (momentarily) side by side (momentarily at the same value of x) at t = 4.0 s?(b) For that value of as, how many times are the cars side by side?(c) Sketch the position x of car B versus time t on Figure. How many times will the cars be side by side if the magnitude of acceleration aB is(d) More than and(e) Less than the answer to part(a)?
