Construction workers are building a new skyscraper in a major city. A crane operator is using a crane to lift a heavy box of supplies (with a mass of 687 kg) to the top of the building when the cord suddenly snaps! The box of supplies free-falls to the ground from a height of 142 m. How many seconds does it take for the supplies to crash into the ground below?
