2.0 m/s 250 kg 200 kg 15 m 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 8 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/s to a speed of 5.0 m/s and then continues at constant velocity untilit strikes car B. Calculate the total time for car A to travel the 15 m. (Use a kinematic equation) (b) After the collision, car B moves to the right at a speed of 4.8 m/s. . Calculate the speed of car A after the collision.

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 8 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/s 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. (Use a kinematic equation)
(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.
i. 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
