Two cars are heading towards one another. Car A is moving with an acceleration of aA = 14 m/s2. Car B is moving with an acceleration of aB = -15 m/s2. The cars are initially at rest and separated by a distance d = 2300 m on the x-axis. At what time in seconds do the cars meet? Now assume that both cars start with an initial velocity. Car A's initial velocity is v0A = 26 m/s and Car B's initial velocity is vB = -26 m/s. At what time, t2 in seconds, do they meet?

Question

Two cars are heading towards one another. Car A is moving with an acceleration of aA = 14 m/s2. Car B is moving with an acceleration of aB = -15 m/s2. The cars are initially at rest and separated by a distance d = 2300 m on the x-axis.

At what time in seconds do the cars meet?

Now assume that both cars start with an initial velocity. Car A's initial velocity is v0A = 26 m/s and Car B's initial velocity is vB = -26 m/s. At what time, t2 in seconds, do they meet?
