question 15

Multiple Choice

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
