A 0.34-kg block rests on a frictionless level surface and is attached to a horizontally aligned spring with a spring constant of 55 N/m.The block is initially displaced 4.1 cm from the equilibrium point and then released to set up a simple harmonic motion.What is the speed of the block when it passes through the equilibrium point?

A) 2.58 m/s
B) 0.74 m/s
C) 1.82 m/s
D) 0.52 m/s
E) 2.35 m/s
