Question

A man who weights 725N sits in a chair. What is the maximum force of friction between the man and the chair of the coefficient of friction is 0.15

Answer 1

Answer:

Explanation:

The weight of the man, R = 725 N

The coefficient of friction, μ = 0.15

The maximum force of friction between the man and the chair is calculated as:

$\begin{gathered} F_r=\mu R \\ \\ F_r=0.15\times725 \\ \\ F_r=108.75N \\ \\ F_r=109N\text{ \lparen to the nearest whole number\rparen} \end{gathered}$
