Native American Indian tribes lived off the land and wildlife in America for many centuries before European settlers arrived here. In many ways, their ways of living were more sustainable than the way in which we do things now. Which of these is NOT a reason the Indians lived more sustainably?

A) They populated the continent far less densely than we do now

B) They considered the land and animals to be their partners, not their property.
C) They were very careful to maintain strict boundaries between tribes and nations.
D) They generally hunted, gathered, and grew what they needed for survival, not more.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
