A 039-Kg Block on a Horizontal Frictionless Surface Is Attached to to an Ideal

question 47

Multiple Choice

A 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is $570 \mathrm {~N} / \mathrm { m } .$ The block is pulled from its equilibrium position at x = 0.000 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 position of the block is $x = 0.057 \mathrm {~m}$ its kinetic energy is closest to

• A) 0.90 J.
• B) 0.84 J.
• C) 0.95 J.
• D) 1.0 J.
• E) 1.1 J.
