Essay
An object with mass m is dropped from rest and we assume that the air resistance is proportional to the speed of the object. If is the distance dropped after t seconds, then the speed is
and the acceleration is
. If g is the acceleration due to gravity, then the downward force on the object is
, where c is a positive constant, and Newton's Second Law gives
.
