Practice Worksheet/Reference Sheet Information: Consider a 2-kg bowling ball that sits on top of a building that is 40 meters tall. It falls to the ground. Think about the amounts of potential and kinetic energy the bowling ball has: as it sits on top of a building that is 40 meters tall. as it is halfway through a fall off a building that is 40 meters tall and traveling 19.8 meters per second. as it is just about to hit the ground from a fall off a building that is 40 meters tall and traveling 28 meters per second.
