A 3.7-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant)is 450 N/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
