Aperson absentmindedly walks off the edge of a tall cliff. they will fall 50 m into either
deadly rocks or a safe lake below the cliff. the lake is 12 meters away from the edge of
the cliff
if the person walks off the cliff at a constant velocity of 3.8 m/s,
will they survive? no (yes or no) how far did they go?

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

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

The upward force acting on the wing of a airplane in flight is known as the "lift" force. (d)
