3. A block with mass \(m\) is dropped on top of a vertical spring with spring constant \(k\) and relaxed length \(L\). The initial
height of the block is \(h\).

L
What is the height of the block when the net force on it is zero? At this height, what can you say about the speed? For
example, will the block be stationary? Will the speed be maximum? Answer using Newton's laws, forces, and kinematics
this time. We'll revisit this system once we've seen more about energy.
