Wall for Ditto (page 18)

bro can you not just specify what you need help with XD

"You help your mom move a 41-kg bookcase to a different place in the living room. If you push with a force of 65 N, what is the coefficient of static friction between the bookcase and the carpet to get the case to begin to move?"

Assume gravity = 10m/s
Normal force of bookshelf = 41 * 10 = 410N
Friction force = Static friction coefficient * Normal force
To get the bookshelf moving, friction force must be less than 65N (your push force)

Assume friction force is 65N
65 = Coefficient * 41
Coefficient = about 1.59
Since you are able to push the bookshelf, the static friction coefficient must be less than 1.59

DEWGONG!! HELL YEAH!!
I mean, uh, Ty selected like five of my answer as BA and, I'm guessing, a few of them also got upvoted a bit, since my points shot up by 120.

hi

hello, Mr. Reptilian Head, being Ambushed by Snow

Hell yeah.

I was hoping that wouldn't happen

shhhhh

Riiggghhhttt....

You have such a way with words.
