Energy in SHM: a 0

Multiple Choice

Energy in SHM: A 0.025-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 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 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
