Ok so there is a typo in the book, either in the question or in the answer. Thank you very much. Its nice to know I was doing the problem correctly

The answer is 2.13 kg*m/s^2 / m The only way I can see to get that answer is to make the cm into decimeters 4.18 cm = 41.8 dec That gives me 2.13 but that wouldn't work for the unit kg*m/s^2 / m

When a 9.09kg mass is placed on top of a vertical spring, the spring compresses 4.18 cm. Find the force constant of the spring. Okay I know the formula for a spring is F=-kx So k=mg/x converting the cm to m I get 4.18cm = 0.0418m So I plug in my numbers k=(9.09kg)(9.81m/s^2)/ 0.0418...
