- Homework Statement
- The coefficient of static friction can be determined using the following procedure. A block is held against a vertical wall by compressing a spring attached to the block as shown below. If the spring has a spring constant = 531 N/m and requires a compression of 3.7 cm to just keep the block from slipping, what is the static friction coefficient between the wall and the 4.5 kg block?

- Relevant Equations
- f=x*k

i would like to understand why my answer is incorrect and how i need to solve this problem
