Studying energy involves determining the amount of energy an object has. This energy can be kinetic or potential, or it could be a combination of both. Consider a 2-kg bowling ball sits on top of a building that is 40 meters tall. It falls toward the ground. Think about the amounts kinetic energy the bowling ball has as it falls, select the when the ball would have the most kinetic energy from the choices given. Question 5 options: A- 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. B- as it sits on top of a building that is 40 meters tall. C- as it is half way through a fall off a building that is 40 meters tall and traveling 19.8 meters per second. D- after it hits the ground and is no longer moving. WILL GIVE BRAINLIEST IF CORRECT
