A particle is connected between two springs on a frictionless, horizontally level track. The other end of each spring is correspondingly anchored to a vertical pin set at opposite ends of the track. If the spring constants are determined to be 1.60 N/m and 3.00 N/m, and the period of oscillation for the block when slightly displaced from equilibrium point is 0.600 second, determine what is the mass of the particle?
