Answer:
The average coefficient of static friction = 0.130
Explanation:
The average coefficient of static friction = [tex]\frac{sum of coefficient of static friction}{number of trials}[/tex]
From the given question, the coefficient of static friction given are:
0.053, 0.081, 0.118, 0.149, 0.180, 0.198
Thus,
the sum of the given coefficient of static friction = 0.053 + 0.081 + 0.118 + 0.149 + 0.180 + 0.198
= 0.779
The average coefficient of static friction = [tex]\frac{0.779}{6}[/tex]
= 0.129833
= 0.130
Therefore, the average coefficient of static friction is 0.130.
