Venus Williams is standing 50 meters away from the fulcrum of a giant seesaw suspended off the side of the Burj Khalifa. You have a 100kg block. Where will you place the block so Venus doesn't plummet 2722 feet to her death?

Protons have a positive charge and, collectively, give an element its atomic number.

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
