Parachute manufacturers provide the fall speed of an open chute as a function of person weight. If we open our chute at 3000​ ft, how long will it take to​ land?   Select all observations that apply below.     A. Gravity opposes the fall of an open chute.   B. Fall speed equals left parenthesis person weight right parenthesis cubed divided by left parenthesis density of air right parenthesisFall speed=(person weight)3/(density of air).   C. It takes 5 minutes to land regardless of person weight.   D. There is little need to make observations.
