In the figure, we must apply a force of magnitude 80.0 N to hold the block stationary at $ x=-3.00 \mathrm{~cm} $. From that position, we then slowly move the block so that our force does +4.00 J of work on the spring-block system; the block is then again stationary. What are the block's positions? ((a) positive and (b) negative) (a) (b)

Question 6 Choose all the correct statements. Use CAPITAL letters in your choices. If you choose more than one, list them in alphabetical order and separate them by comma. A. $\sin^{-1} x = \frac{1}{\sin x}$ B. $\arcsin(-\frac{\sqrt{2}}{2}) = -\frac{\pi}{4}, \frac{7\pi}{4}$ because $\sin(-\frac{\pi}{4}) = -\frac{\sqrt{2}}{2}$ and $\sin\frac{7\pi}{4} = -\frac{\sqrt{2}}{2}$ C. $\sin^{-1}\frac{\sqrt{2}}{2} = \frac{3\pi}{4}$ because $\sin\frac{3\pi}{4} = \frac{\sqrt{2}}{2}$ D. $\sin^{-1}\frac{\pi}{4} = \frac{\sqrt{2}}{2}$ because $\sin\frac{\pi}{4} = \frac{\sqrt{2}}{2}$ E. None of the above. ? A ? B ? E only ? C ? D
