The motion of a block-spring system is described by the equation x = A sin (ωt), where x is the displacement, A is the amplitude, ω is the angular frequency, and t is the time.

The potential energy (PE) in a spring system is given by PE = 1/2 kx², where k is the spring constant. The kinetic energy (KE) is given by KE = 1/2 mv², where m is the mass of the block and v is the velocity.

At the point where the potential energy equals the kinetic energy, we have 1/2 kx² = 1/2 mv².

We know that the velocity v = dx/dt = Aω cos(ωt).

At t = 2.00 s, we have x = A sin (ω*2.00) and v = Aω cos(ω*2.00).

Substituting these into the energy equation gives us 1/2 k(A sin (ω*2.00))² = 1/2 m(Aω cos(ω*2.00))².

Solving this equation for ω will give us the angular frequency of the system.

However, without the values of A, k, and m, we cannot solve this equation.

Please provide the values of A, k, and m to proceed.
