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

Multiple Choice

A 2.0-kg block on a frictionless table is connected to two springs whose opposite ends are fixed to walls, as shown in the figure. The springs have force constants (spring constants) k₁ and k₂. What is the oscillation angular frequency of the block if $k _ { 1 } = 7.6 \mathrm {~N} / \mathrm { m }$ and $k _ { 2 } = 5.0 \mathrm {~N} / \mathrm { m } ?$
