Moving a 250kg Elephant with 425N Force

[physicshard22]

Homework Statement

A boy puts a 250kg elephant on a piece of carpeting and slides it across the floor by exerting a horizontal force of 425N on the elephant

Homework Equations

Ff = uKFn

The Attempt at a Solution

Fn = Fg
Fnet = Fap - Ff
Fnet = 425 - Ff
ma = 425 - uKFn
250a = 425 - uK(2450)

 

[itr]

what is the question asking?

 

[physicshard22]

for coefficient of kinetic friction

 

[itr]

mue=f max/fn
425N/(250x9.81)
mue=.173

I believe that's how you do it

 

[physicshard22]

why is friction 425N

 

[itr]

its force
