A block is released from rest, at a height $h$, and allowed to slide down an inclined plane. There is friction on the plane. At the bottom of the plane, there is a spring that the block will compress. After compressing the spring, the block will slide up the plane to some maximum height, $h_A$, after which it will again slide back down. How much work is done on the block between its release at height $h$ and its ascent to its next maximum height?
1. $2\mu m_A g h_A$
2. 0
3. $m_A g (h - h_A) + 2\mu m_A g h_A$
4. More information is needed.
5. None of these
6. $m_A g (h - h_A)$
