well there's a constant force aplied to the car, so its accelerating. oh okay, so how does the flat surface slipping works

in my case i have a car going on a flat surface for few meters, then goes up a ramp. does slipping occur when it rolls down(when it tries to go up)? i.e. friction force > F applied?

... then how does it slip..?

wouldn't that mean the object would accelerate? I'm really confused

So I am trying to figure out under what circumstances slipping usually occur, and what causes it to occur. lets assume we have a cart, and there is a static friction mu between the surface and the wheel. let's say the cart is being pushed at F horitonztally. Fs, force of friction...

can anyone verify this? my 1st column came out to be a = t b = -2 -2t c = 5/3 +t and 2nd column d= s e= 1-2s f= -2/3+s

thanks for the replies. I see how it's more intuitive to do it the algebraic way, so I'll just discard the inverse trick. Using the rref makes it pretty simple, but when i reduce the one on the left side, do I reduce it on the right as well, if say we're given a matrix other than an I_n ?
