Question 227699
friction with the air (or any fluid) will act against the gravitational force that accelerates a falling object
___ this is why skydivers reach a "terminal velocity"; the force of atmospheric friction equals the force of gravity


time = velocity / acceleration


distance = 1/2 * acceleration * (time)^2


substituting ___ distance = 1/2 * (velocity)^2 / acceleration


d = 1/2 * (39.2)^2 / 9.81 = 78.3
