Question

question 8 of 10
you slide across a wooden floor in your socks. there is a normal force of 1033 n acting on you, and the coefficient of kinetic friction is 0.21. what is the force of friction acting on you as you slide?
a. 289 n
b. 358 n
c. 217 n
d. 331 n

Explanation:

Step1: Recall friction - force formula

The formula for the force of kinetic friction is $F_f=\mu_kF_N$, where $F_f$ is the force of kinetic friction, $\mu_k$ is the coefficient of kinetic friction, and $F_N$ is the normal force.

Step2: Substitute given values

We are given that $\mu_k = 0.21$ and $F_N=1033$ N. Substitute these values into the formula: $F_f=0.21\times1033$.

Step3: Calculate the result

$F_f = 0.21\times1033=216.93\approx217$ N.

Answer:

C. 217 N
