Mass on a Spring: A 0.16-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is 360 N/m. The block is pulled from its equilibrium position at x = 0.000 m to a position x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. When the position is x = -0.037 m, what is the acceleration of the block?

A. 83 m/s2
B. 43 m/s2
C. 64 m/s2
D. 270 m/s2
E. 370 m/s2
