The wave function of a point particle of mass m subject to some spherically-symmetric potential v(r) is given in cartesian coordinates by (x + y + 3z) f(r), ψ(x) for some given function j (r), where as usual y = (a) what are the possible results if the magnitude |l of the angular momentum is measured? (b) what are the possible results if the z-component l of the angular momentum is measured simul +v taneously with l? (c) suppose it is known that (x) is a stationary state with energy e. what can be deduced about the potential v(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
