Car A is 15 m away from car B and moving to the right at 2.0 m/s, as shown, when the driver decides to bump into car B, which is at rest. Car A accelerates at 1.5 m/s2 to a speed of 5.0 m/s and then continues at constant velocity until it strikes car B. Calculate the total time for car A to travel the 15 m.

The question makes literally no sense, "when the driver decides to bump into car B, which is at rest. Car accelerates at 1.5m/s2 to a speed of 5.0m/s and then continues at constant velocity until it strikes car B" I think you may have copied it here incorrectly.
