To calculate the kinetic coefficient of friction is closest to: 1. 0.23.
<u>Given the following data:</u>
- Horizontal force = 4.5 Newton
To calculate the kinetic coefficient of friction:
Mathematically, the kinetic force is given by this formula;

<u>Where;</u>
represents the kinetic force.
is the normal force.
- μ represents the kinetic coefficient of friction.
Making μ the subject of formula, we have:

Substituting the given parameters into the formula, we have;

u = 0.225 ≈ 0.23

Just look at the periodic table and google how to read an element from the periodic table. A picture of a single cell from the table will pop up with arrows of what's what and it will help you answer this in no time! (Brainliest please)
