A 0025-Kg Block on a Horizontal Frictionless Surface Is Attached to to an Ideal

question 22

Multiple Choice

A 0.025-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 150 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. When the displacement is x = 0.024 m, what is the kinetic energy of the block?

• A) 0.44 J
• B) 0.41 J
• C) 0.46 J
• D) 0.49 J
• E) 0.52 J
