A particle of mass m = 0.40 kg oscillates on the end of a spring with an amplitude of 0.30 m. At t = 0, it's at it's equilibrium position (x=0) and is moving in the positive x-direction. At 0.20 s later it is at x = 0.25 m.

a. What is the lowest possible value for the spring constant?

b. What is the second lowest possible value for the spring constant?
