several students are riding in bumper cars at an amusement park. the combined mass of a 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 m/s when the driver decides to bump into car B, which is at rest. car A accelerates at 1.5 m/s2 to a speed of 5 m/s and then continues at constant velocity until it strikes car B. Calucalte the total time for car A to travel the 15 m. 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. after the collision did car A move to the left, right, or is at rest? is this an elastic collision?

haha i had this same assignment at school like 2 weeks ago

(a) t = 2s, d = 7m, t = 1.6s, so overall t = 3.6s

(b)1.16 m/s to the right

(C)before: 3125, After:2449J, therefore not elastic
