A horizontal spring attached to a wall has a force constant of k = 830 N/m. A block of mass m = 1.60 kg is attached to the spring and rests on a frictionless, horizontal surface as in the figure below.
C) What is the speed of the block when it is at a position xi/2 = 2.90 cm?
I already got part A and B, but I can't seem to get part C. Any help is appreciated.

w = √(k/m) = 22.776 rad/sec
Assuming xi means the initial deflection of the mass, it also is equal to the amplitude A of the motion:
V = w*A*sinΘ
When x = A/2, Θ = 60°. Using the formula above,
V = 22.776*(0.058)*sin60° = 1.144 m/s
