question 18

Multiple Choice

A 3.7-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is $450 \mathrm {~N} / \mathrm { m }$ 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.The maximum elastic potential energy of the system is closest to

• A)1.4 J.
• B)1.3 J.
• C)1.6 J.
• D)1.7 J.
• E)1.8 J.
