Question

One of their side jobs is a safe delivery and installation. A pulley system is used to lift the safe 2 meters above the ground. But the rope snaps! To avoid cracking from any drops, a large, stiff spring is placed below the safe while it's lifted. If the 1200 kilograms safe hits the spring and compresses 17 centimeters, what's the spring constant of the spring?
