A block of mass m is attached to a spring of spring constant k is free to oscillate with angular velocity ω in a horizontal plane without friction or clamping. It is pulled to a distance x0 and pushed towards the center with a velocity v0 at time t = 0. The amplitude of oscillations in terms of ω,x0 and v0 is
A. √v2₀²/ω2−x²₀
B. √ω²v²₀+x²₀
C. √x²₀ω²+v²₀
D. √v₀ω²+x²₀
