Two asteroids orbit each other at a distance of 1.96 x 10 m. As they orbit each other, they each experience a gravitational force of 1.88 x 1011 N. One of the asteroids has a mass that is four times the mass of the other
asteroid.
Calculate the mass of the lighter asteroid.
PLEASE ANSWER QUICKLY

From negative to negative

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
