• Many times we are asked how long it takes a person to fall and how fast they were going. This table is an attempt to answer that question using a data table that skydivers use to estimate their free fall time.
• For example, after six seconds an average‐sized person will have fallen 504 feet. Over the last second they will fall about 138 feet, averaging a speed of about 95 miles per hour.
• After about 12 seconds the person falls no faster, so for every additional second the person would fall another 174 feet at a speed of about 118 miles per hour.
