4. Suppose you found a new simulated galaxy that is traveling 5.1 centimeters per second (or 2 inches, if you used inches). How far would this galaxy be from the Milky Way at the end of the simulation?

Why the rest of the question?

The rocks expand when there hot/warm  and contract when they are cold.

Answer body lying face up ;

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
