I have a question..(adsbygoogle = window.adsbygoogle || []).push({});

A shopper pushes a 6.5kg shopping cart up a 13 degree incline, heading east. Find the magnitude of the horizontal force, F, needed to give the cart an acceleration of 1.61 m/s2 (seconds squared).

This is what I have done.

sigmaFx= F(what I'm trying to find) - Fg,x - Ff

MAnet = F - mgsin(theta) - u(mieu)Fn

F = MAnet + mgsin(theta) + uFn

F = (6.5kg)(1.61m/s2) + (6.5kg)(9.81m/s2)sin13 +u(63.13070718N)

And here's where I'm stuck because there's two variables. Does anyone know what I'm doing wrong?

The answer should be in Newtons
