To calculate the kinetic coefficient of friction is closest to: 1. 0.23.
<u>Given the following data:</u>
- Horizontal force = 4.5 Newton
- Normal force = 20 Newton
- Speed = 3.0 m/s
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
