Wile E. Coyote and the Roadrunner are fictional cartoon characters. The premise of the cartoon is that Wile E. Coyote unsucessfully tries to catch the very fast and clever Roadrunner. Wile E. and his wagon (still with a combined mass of 100 kg) are moving along with a velocity v1 = 10 m/s i. Wile E. spots the Roadrunner on another wagon (whose combined mass is also 100 kg) moving along with a velocity v2 = -10 m/s i. Wile E. takes out his magic Super Glue and puts it in front of his wagon. After colliding the two wagons stick together. What is the velocity of the combined system of two wagons plus occupants after the collision?
