Magnetic Field and spring constant

[rinspd]

An unknown mass M is found to have a period of oscillation of 1.0 second using a spring of unknown spring constant k. When an additional 200g is added to the initial mass, the period of oscillation increases by 0.6 seconds Determine: (a) The unknown mass M (g), (b) The spring constant k (N/m), and (c) the mass corresponding to an oscillation period of 2 seconds for this spring.
