spring hangs from the ceiling with an unstretched length fxo = 0.61 m. A m₁ = 8.7 kg block is hung from the oring, causing the spring to stretch to a length 1 = 0.74 m. ind the length x2 of the spring when a m2 = 2.9 kg block =hung from the spring. For both cases, all vibrations of the spring are allowed to ettle down before any measurements are made. x2 = m m m₂
