Homework Equations
d2y/dx2+(k/w)y=o
The Attempt at a Solution
I can't figure out exactly what they r asking me here- do I get my k from the first sentence making k=24 and w=3/8 and use the the others asy(0)=1/3 and y'(0)=8, or are they asking me to use the 2nd weight and add it to the first and if so, how? is that an added force? I am really confused be the wording of this problem.
