Two blocks are connected by a rope as shown.
Block m2 with mass kg hangs freely from the rope.
Block m1 with mass kg is connected
to the other end of the rope, and is on a rough surface with coefficient of friction 
= .
It is also also connected to a spring with spring constant k= N/m.
When released, m2 will move down and m1 will move toward the right, until the spring's stretch
stops the system. The question is: how far will m1 move before the system stops? (your answer will
also correspond to how much the spring stretches and how far down m2 will move).
