1. The problem statement, all variables and given/known data A mass m slides on a frictionless horizontal surface, connected to two springs. If the springs have force constants k1 and k2, show that the simple harmonic sliding motion has period: T = 2pi*sq root(m(k1+k2)/(k1k2) There is a diagram and the springs are connected horizontally to each other and then attached to the mass. 2. Relevant equations T=1/f f=1/2pi*sq root(k/m) 3. The attempt at a solution I figured out that for one spring T=2pi*sq root(m/k1), but i dont understand how to get k1k2 at the bottom of the equation that i need to show.
