A 20 Kg Block on a Frictionless Table Is Connected to to Two

A 2.0 kg block on a frictionless table is connected to two ideal massless springs with spring constants k₁ and k₂ whose opposite ends are fixed to walls,as shown in the figure.What is angular frequency of the oscillation if k₁ = 7.6 N/m and k₂ = 5.0 N/m?

A) 2.5 rad/s
B) 3.5 rad/s
C) 0.40 rad/s
D) 0.56 rad/s
