Answer to Question #192073 in Physics for Nique

Question

An object that has a mass of 36.0 kg is pushed along a horizontal surface with a force of 85.0 N. 

If the acceleration of the object is 0.361 m/s

2

, what is the coefficient of friction between the 

object and surface? Include a labelled FBD for the object. 

Answer 1

$$ma=F-\mu mg\\(36)(0.361)=85-\mu (36)(9.8)\\\mu=0.204$$
