A 016 Kg Block on a Horizontal Frictionless Surface Is Attached

A 0.16 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 360 N/m.The block is pulled from its equilibrium position at x = 0 m to a displacement x = +0.080 m and is released from rest.The block then executes simple harmonic motion along the x-axis (horizontal) .When the displacement is x = -0.037 m,the acceleration of the block is closest to:

A) 85 m/s²
B) 43 m/s²
C) 64 m/s²
D) 270 m/s²
E) 370 m/s²
