Its a pull and the location has to be less than 400N
To find k
You can do
C-a((b/2)^2))
This is because when you complete the square you have the c value that you have initially minus the new c value which is found by (b/2)^2 and if you factored a number out then multiply it to that.
So in this case
31- 1(10/2)^2
31-(5)^2
31-25
6
That is 6120.43 yen rounded to the nearest hundredth because if you exchange 56.92 at a rate of 1 yen is equal to 0.0093 you get 6120.43.
