Question

HELP PLEASE! The distance d that an object falls is directly proportional to the square of the time of the fall,t. A person who is parachuting for the first time is told to wait 12 seconds before opening the parachute. If the person falls 64 feet in 2 seconds, find how far he falls in 12 seconds.

distance is ___ feet

Answer 1

since distance is proportional to t^2, then since 12 = 6*2, the distance fallen in 12 seconds will be 36 times the distance fallen in 2 seconds.
