Experiment 1 Rupert finds that if he attaches a 430.0 gram mass to the hook, and then very slowly lowers the mass with his hand until the force on the mass by the spring is as large as the weight of the mass, that the spring stretches by 39.0 cm A Second Experiment with the Vertical Mass-Spring System Rupert now plans to try a second experiment. He will use the same mass, and once again the experiment will begin with the mass...
