Homework Statement
When a 9.10 kg mass is placed on top of a vertical spring, the spring compresses 4.22 cm.
Find the force constant of the spring.
Homework Equations
F=kx
F=ma
The Attempt at a Solution
I know that Fgravity should =Fspring so I set the two above equations equal to each other and plug in the proper values.
I will also convert the cm to meters so my answer has the correct units.
9.10(9.81)=k(.0422)
89.271/.0422=k
k=2115.43
It wants the answer in kN/m
I put 2120 first, because I thought it had the right number of sigfigs, but that was wrong.
So then I put in my exact answer which was also wrong.
What am I doing wrong?
