hi okgo! :wink:

you need to use good ol' Newton's second law (F = ma) twice …

show us what you get :smile:

hmm so far..
m= mass of box and M=mass of cart. I assume the acceleration of the box and cart is the same.

F(box)=force(friction)=umg=ma
ug=a

F(cart)=force done by you=Ma
Substitute ug=a into the equation.
u*g*M=Force so mass of the box doesn't matter?

F(cart)=force done by you=Ma
Is that for the cart M or for both M and m?
