Thank you!

https://www.physicsforums.com/threads/determine-normal-force.959335/ In here there is my attempt at a solution but I'm not sure if that's the right answer..

How do I express force and acceleration as single magnitude? Don't they have different units? And how do I express with number of degrees? I've been looking for how to do that for about 20 mins but I'm not sure..

So then may I use the same compass directions as the question provides me with the final answer? For example, Fnetx= 678.2 N of E and Fnety= 178.4 S of E?

Homework Statement Dylan is rushing to catch a flight. As he walks in the airport he pulls his suitcase behind him, which is rolling on its wheels. The mass of the suitcase is 20.0kg. Dylan pulls on the handle so that he exerts a force on the handle of 100N, 30° above the horizontal. Determine...

Oh, I see.. I thought I'm only getting Fnet in the x axis! Thank you.. Then is the answer for x force=+678.2N, acceleration=+7.54m/s/s & y force=-178.4N and acceleration=-1.98m/s/s?

Sorry for asking you a lot of questions.. I just want to make sure everything's correct:)

I think it's only Fby that is a negative number because like you said, I'm considering E as positive. Is that right? But in that case, my answer won't change, right?

Oh! so are you telling me that Fbx= -225N and Fby=-389.7N or only Fby=-389.7N?

Yes. Anything that is not with negative signs have positive sign to them. Could you please tell me if my attempt at a solution is correct or not?

Homework Statement Two linebackers simultaneously hit a quarterback, who has a mass of 90 kg. One linebacker exerts a force on the quarterback of 500 N, 25° N of E. The other linebacker exerts a force on the quarterback of 450 N, 60° S of E. Determine the net force acting on the quarterback...
