Two spaceships pass one another in opposite directions a a relative speed of 0.8c. an observer in spaceship 1 measures the length of spaceship 2 to be three fifths the length of her own ship. a) what is the ratio of the rest lengths of the two spaceships? b) what will an observer in spaceship 2 determine as the length of spaceship 1?

Sublimation- which change of state is shown in model

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
