question 40

Multiple Choice

A 1.6-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 190 N/m. The block is pulled from its equilibrium position at x = 0.00 m to a displacement x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. What is the velocity of the block at time t = 0.40 s?

• A) 0.82 m/s
• B) -0.82 m/s
• C) 0.30 m/s
• D) -0.30 m/s
• E) 0.00 m/s
