Tyler is in downtown San Antonio entertaining the tourists with amazing feats of physics. He carries a nickel (mass of 5.0 grams) up to the top of the Tower of the Americas and places it on the edge of the observation
deck, a height of 124 meters. Tyler pushes the nickel off the edge of the Tower, and then tells the tourists
that he will be able to calculate the velocity of the nickel just before it hits the ground. What will be the
nickel's velocity?
