An empty cart, tied between two ideal springs, oscillates with ω = 10.1 rad/s.A load is placed in the cart, making the total mass 3.9 times what it was before. What is the new value of ω?

rad/s

This is how I did it, but its wrong

3.9/3=1.3 then 1.3x10.1=13.13 rad/s

I don't know what I am doing wrong.
