Problem: An unscratched spring hangs from the ceiling with a length of 0.61 m. An 8.3-kg block is hung from the spring and the spring stretches to be 0.90 m long. For both cases, all vibrations of the spring are allowed to settle down before any measurements are made.
Part A: How long will the spring be if a 2.9-kg block is hung from the spring?
