An ideal spring is in equilibrium, hanging from a ceiling with a 1 kg mass at the end. At rest, the length of the hanging spring is 10 cm. Then, an additional 5 kg block is added to the spring, causing its length at rest to increase to 13 cm. The 5 kg block is then removed. Starting from rest, when the 5 kg block is removed, the spring begins to oscillate. What will the spring’s velocity be, the third...

A spring is hanging from the ceiling. When a 2 kg mass is hung from the spring, the spring has a total length of 50 cm. When a 5 kg mass is hung from the spring, the spring has a total length of 70 cm. Determine the spring's relaxed length and its spring's spring constant. (You should keep 4 decimals in your values to avoid rounding errors.)
