Story: A worker in the pets department of the Jackson, Ohio Walmart Supercenter was choosen to bungee-jump from a tower to celebrate the grand opening of the store. The tower is 80 feet high and to light up an event(it takes place in the evening), a spotlight is brought in and is on a pole 80 feet high and is positioned 20 feet away from the bungee tower. Early shoppers may get a chance at a furby. Some customers complained that the enigma page only has one left! We should thank the customer service people for putting up with all the crap! People are encouraged to buy rye bread and throw it at the falling employee.... As she falls (function given: {s(t)= - 16t^2} where s is distance and t is time.), people notice a shadow on the ground (assuming the ground is flat).
Enigma: How fast does the SHADOW move along the ground 2 seconds after she jumps (80 feet above the ground). (This is the same question with story changed as my latest calculus test).
