Several students are riding in bumper cars at an amusement park. The combined mass of car A and its occupants \nis 250 kg. The combined mass of car B and its occupants is 200 kg. Car A is 15 m away from car B and moving \nto the right at 2.0 m\/s, as shown, when the driver decides to bump into car B, which is at rest. \n(a) Car A accelerates at \n2\n1.5 m s to a speed of  5.0 m s and then continues at constant velocity until it strikes \ncar B. Calculate the total time for car A to travel the 15 m."}
