First find the acceleration:
F = m × a
13 = 36 × a
a = 0.36 m/s²
Now find the distance:
s = u×t + a×t²/2
s = 0×4.1 + 0.36×4.1²/2
s = 3 m

Well, since the cart is loaded, it doesnt move that far because it's stumbling so much. If I'm loaded, generally speaking I'll make it no further than a couple feet. If I'm pushed. Maybe a foot or two farther.
However, if it's an attractive woman pushing me, well that's another story altogether. I'll move all night long and not rest a wink...
