(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 23-kg suitcase is being pulled with constant speed by a handle that is at an angle of 25 degrees above the horizontal. If the normal force exerted on the suitcase is 180N, what is the force applied to the handle?

2. Relevant equations

net force =ma[tex]\vec{}[/tex]

Voy = Vo sin [tex]\theta[/tex]

3. The attempt at a solution

I didn't know exactly how to approach the problem. At first I wanted to label the y axis or normal force 180 n, set it equal to x sin 25, and solve for x. I feel like the mass of the suitcase (assume it is mass or is it weight?) has a part to play, but in reality, my teacher just does a bad job. -next step?
