Several students are riding in bumper cars at an amusement park. The combined mass of car A and its occupants is mA = 252 kg. The combined mass of car B and its occupants is mB = 208 kg. Car A is 16 m away from car B and moving to the right at vAi = 2.1 m/s, as shown, when the driver decides to bump into car B, which is at rest.(a) Car A accelerates at 1.5 m/s2 to a speed of 4.9 m/s and then continues at constant velocity until it strikes car B. Calculate the total time for car A to travel the 16 m.
