Cars A and B move in the same direction in adjacent lanes. The position x of car A is given in the figure, from time t = 0 to t = 7.0 s. The figure's vertical scaling is set by xs = 48.0 m. At t = 0, car B is at x = 0, with a velocity of 18.0 m/s and a negative constant acceleration aB. (a) What must aB be 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 aB, how many times are the cars side by side? How many times will the cars be side by side if the magnitude of acceleration aB is (c) more than and (d) less than the answer to part (a)?

Cars A and B move in the same direction in adjacent lanes. The position of car A is given in the figure. At t=0, car B is at x=0, with a velocity of 10 m/s and a negative acceleration. What must be that acceleration such that the cars arc side by side when t=6 sec? For that value of the acceleration, how many times will the cars be side by side?

Two cars A and B approach each other in two adjacent lanes of
a linear track in opposite directions, as shown in the figure. at t
= 0s, A and B are at D = 21m away, the car A departs from rest and
moves with a constant acceleration of aA = 2m / s ^ 2 and auto B
moves with constant velocity of Vb = 4m / s.
