kx2/2 = mv2/2; v = x√k/m = 0.016√12.5/2.5 = 0.0358 m/s = 3.58 cm/s

Dear math tutor. Could you please next time mention the law of conservation of energy? Math calculations are easy. First of all you need to show principles of physics in any problem. I also recommend you to make yourself familiar with the theory of measurements. Then you would know that in this case the answer should be rounded to 3.6 cm/s.
