1. The problem statement, all variables and given/known data A block of mass m, is suspended by a spring with a spring constant k and stretches a length x . If two blocks of mass m/2 are suspended by a spring with the same spring constant k (ii), how much will the spring stretch? http://imagizer.imageshack.us/v2/800x600q90/12/sidr.png [Broken] 2. Relevant equations Fg=mg Fe=-kx 3. The attempt at a solution I think each mass of m/2 stretches the spring x/2, so together would stretch the same as the block of mass m alone.
