Tired worker pushes with a horizontal force of 357 n on a 142 kg crate initially resting on a thick pile carpet. the coefficients of static and kinetic friction are 0.60 and 0.40, respectively. find the magnitude of the frictional force exerted by the surface.

Frictional force will be equal to 257 N

Explanation:

We have given mass m = 142 kg

Static frictional coefficient and kinetic coefficient friction

Force applied F = 357 N

Static friction force is given by

As static friction is greater than the force applied

So body will not move

And friction force will be equal to 257 N

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
