A block of mass 0.379 kg is placed on the end of a spring which has a stiffness of 216 N/m. It is pulled down 4.40 cm and released. What is the frequency of oscillation?
What is the period of oscillation?
So let's flip this around. Suppose you know that a spring has a spring constant of 3.30 N/m. When set in motion, a block attached to the spring oscillates with a period of 2.80 s. What is the mass of the block?
