Consider the following discussion between two students about the different properties of light. Student 1: I think I get how light works. If you look at the chart of the electromagnetic spectrum, it shows that light with a higher frequency will also have a long wavelength. But all has the same speed Student 2: I disagree. If one type of light has a lot of energy and a high frequency, it will have a faster speed than light that has a lower energy and a low frequency. Do you agree or disagree with either or both of the students

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

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

45 is the correct answer
