Two cars are heading toward one another. The cars were initially at rest and separated by a distance of 3200 m. Car A is moving with an acceleration of 7 m/s2. Car B is moving with an acceleration of -11 m/s2. Assume that they are on the x-axis.

a) at what elapsed time, in seconds, do the cars meet?
b) what is the displacement, in meters, of Car A at the time the cars meet?
c) what is the displacement, in meters, of Car B at the same time the cars meet?
d) Now, assume that both cars start with an initial velocity. Car A's initial velocity is VA,0 = 23 m/s and Car B's initial velocity is -17 m/s. At what time, in seconds, do they meet?
