In the laboratory, you attach 300 g mass to a spring of negligible mass and start oscillating it. The elapsed time from when the mass first moves through the equilibrium position to the second time it moves through that position is 2 s. Find the force constant of the spring

**drwls**, Saturday, February 16, 2013 at 7:13amThe oscillation period is P = 2.0 s.

Use the formula

P = 2*pi*sqrt(M/k)

with M = 0.300 kg

Solve for k in Newtons per meter

k = 4*pi^2*M/P^2
