A block with mass m $=6\mathrm{.}8$ kg is attached to two springs with spring constants kleft$=35$ N$/$m and kright$=56$ N$/$m$.$ The block is pulled a distance x $=0\mathrm{.}28$ m to the left of its equilibrium position and released from rest.If the block had been given an initial push, how would the period of oscillation change?

the period would increase

the period would decrease

the period would not change
