put this solution on YOUR website!If a spring stretches 0.6m when-kg weight is attached to it, how much will it stretch when a 10-kg weight is attached to it?
--------------------
If you meant a 1 kg to stretch it 0.6 meters, then:
it will stretch 10 times as much, or 6 meters. That's a lot of extension, and this will not be true if Young's modulus is exceeded, but I doubt that's taken into consideration in this problem.
