1. The problem statement, all variables and given/known data A 0.296 kg mass is attached to a spring and executes simple harmonic motion with a period of 0.18 s. The total energy of the system is 3.3 J. Find the force constant of the spring. Answer in units of N/m. 2. Relevant equations k=m(t/2[tex]\pi[/tex])^2 3. The attempt at a solution k=296(0.18/2[tex]\pi[/tex])^2 I get 0.0002429276699 but it is wrong. Any ideas what i did wrong?
