1. The problem statement, all variables and given/known data A 0.31-kg mass is hanging from a spring with spring constant 13 N/m. Then the mass is displaced from the equilibrium by 3.3 cm and let go. 2. Relevant equations for frequencthy the equation would be 1/T 3. The attempt at a solution to T I would use this equation 2∏sqrtm/k 2∏sqrt0.033m/13N/m= 0.316566651s 1/0.316566651s= 3.158892436Hz I got this wrong but, this is the only equation for frequency that I was taught in class. What did I do wrong.
