Addition to Impulse-Momentum Task Cards 21 - Two bumper cars at an amusement park collide elastically as one approaches the other directly from the rear. The car in front (CarA) has a mass of 550 kg and the car behind it (CarB) has a mass of 450kg. The car in front was traveling at 3.70 m/s while the car behind hit him with a velocity of 4.50m/s. What are their final velocities after the collision? 22- A 2200 kg car traveling at 30m/s collides with another 2200 kg car that is at rest. The two bumpers lock and the cars move forward together. What is their final velocity? before collision after collision X
