Jimmy and his cart (with a combined mass of 200 kg) are moving along with a velocity v1 = 20 m/s i. Jimmy spots Margy in another cart (whose combined mass is also 200 kg) moving along with a velocityv2 = -20 m/s i. There is tape on the front of Jimmy's cart. After colliding the two carts stick together. What is the velocity of the combined system of two carts plus occupants after the collision?
