A can of Coke moving 16.6 m/s towards the right(the positive direction) collides with a can of Pepsi moving 3.67 m/s toward the left, and both cans are badly crushed. If the final velocity of the can of Coke is 3.74 m/s still toward the right, then what is the final velocity of the can of Pepsi? Assume the two cans have equal masses.
