When a 0.30-kg mass is attached to a vertical spring, the spring stretches by 15 cm. How much mass (total) must be attached to the spring to result in a 0.86-s period of oscillation?
A vertically oriented spring is 0.49m in length when placed on a table. If when you place a 20N weight on the spring, the spring compresses to new length of 0.33m, then what is the spring constant for this spring?
