"Punkin Chunkin," or Pumpkin Chunking, is the sport of launching pumpkins with cannons and other mechanical devices as far as possible. Teams that compete in these
events have names such as American Chunker Inc., Fibonacci Unlimited II, Shooda Noed
Beter, and Snot Rocket. The world record was set in 2013, when a pumpkin was launched
to a height of 2250 feet and a distance of 4500 feet (measurements have been rounded
for simplicity). Assume the motion of the pumpkin was symmetrical. Write a quadratic
expression to relate the vertical displacement y, with the horizontal displacement x. How
high was the pumpkin when it was 100 ft away?
