Several students are riding in bumper cars at an amusement park. The combined mass ofcar A and its occupant is 250 kg. The combined mass of car B and its occupant is 200 kg.Car A is 15.0 m away from car B and moving to the right at 2.0 m/s as shown. The driver of car A decides to bump car B which is at rest. Car A accelerates at 1.5 m/s2 to a top speed of 5.0 m/s and then continues at a constant velocity until it strikes car B.
a) Calculate the total time for car A to travel the 15.0 m.
b) After the collision, car B moves to the right at a speed of 4.8 m/s. Calculate the velocity of car A after the collision.
c) Is this a completely elastic collision? Justify your answer.
