Question

a bookcase has a mass of 38 kg and the coefficient of friction between it and the floor is 0.82 what is the maximum force of friction between the bookcase and the floor A 372N B 305N C 412N D 449N

Answer 1

yea its b 305

Step-by-step explanation:

Answer 2

The correct answer is B) 305 N.

The maximum force of friction between the bookcase and the floor is given by

`F=\mu m g`
where

`\mu=0.82` is the coefficient of friction

`m=38 kg` is the mass of the bookcase

`g=9.81 m/s^2` is the gravitational acceleration.

By substituting the data of the problem into the formula, we find

`F=(0.82)(38 kg)(9.81 m/s^2)=305 N`
