A box of mass 35g is attached to a horizontal spring with a spring constant of 131 N/m. The spring is then extended by 14 cm, and the box is subsequently released. Calculate the speed of the box at the moment when the entire elastic potential energy is converted to the box's kinetic energy. Give your answer to 2 decimal places if needed.

A) 1.29 m/s
B) 1.82 m/s
C) 2.05 m/s
D) 2.41 m/s
