At t = 6 hours? At t = 12 hours? Draw in each of these locations and connect the path between the stars. For what fraction of the day is star B visible? d)Draw in C at the specified coordinates (as best you can) and assume that this is time t = 0 hrs. Estimate the coordinates of the star at t = 6 hours? At t = 12 hours? At t = 24 hours? For what fraction of the day is star C visible?

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

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )
