Question:
Find the kinetic energy [tex]K[/tex] of the block at the moment labeled B. Express the answer in terms of [tex]k[/tex] and [tex]A[/tex].
Well, I know the potential energy at point B. That's [tex]U_B = (1/2)(k)(\frac{1}{2}A^2) = \frac{1}{8}kA^2[/tex].
How am I supposed to find the kinetic energy?
