Using the total moment of inertia I of the system found in Part D, find the total kinetic energy K of the system. Remember that both particles rotate about the y axis. Express your answer in terms of m, ω, and r.

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

The big glowy thing is called the sun it is a star in our galaxy and is over 1 million degrees

Since the pully is a simple machine so the mechanical advantage is a 1
