(1) A refrigerator with mass(adsbygoogle = window.adsbygoogle || []).push({}); mis pushed up a ramp at constant speed by a man applying a forceF. The ramp is at an angle [tex] \theta [/tex] above the horizontal. Neglect friction for the refrigerator. If the forceFishorizontal, calculate its magnitude in terms ofmand [tex] \theta [/tex].

Ok so I drew a free body diagram. The forces acting on it are the applied forceF, the weight of the crate [tex] w = mg [/tex], and the normal forcen. I set up a coordinate system in which the side parallel to the ramp is the x-axis, and the side perpendicular to the ramp is the y-axis. So I decomposed the weight vector into its following components: [tex] F_{x} = mg\sin\theta [/tex], and [tex] F_{y} = mg\cos\theta [/tex]. I know the answer is [tex] mg\tan\theta [/tex]. How would you get this knowing the components of the weight vector?

Thanks
