Several students are riding in bumper cars at an amusement park. The combined mass of car A and its occupants is 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 to the right at 2.0 m/s, as shown, when the driver decides to bump into car B, which is at rest.
Several students are riding in bumper cars at an amusement park. The combined mass of car A and its occupants is 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 to the right at 2.0 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 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.
(b) After the collision, car B moves to the right at a speed of 4.8 m/s .
i. Calculate the speed of car A after the collision.
ii. Indicate the direction of motion of car A after the collision.
____ To the left ____ To the right ____ None; car A is at rest.
(c) Is this an elastic collision?
____ Yes ____ No
