A skater travels in a straight line 8.5*10^2m[25 degress N of E] and then 5.6810^2m in a straight line [21 degrees E of N]. The entire motion takes 4.2 min. What is the skater's displacement?

Question

istim · Answer

I've tried 2 different methods. Cos Law and Pythagorean Theorem. Re-doing Cos Law right now cause I think it was my calculator's fault (rads instead of degs)

istim · Answer

I'm done. Dissappointing end result.

I see...
so I got it wrong and you got it right

istim · Answer

Really?

turingtest · Answer

$$1311.83m\approx1.3\times10^3m$$so yeah, lol

istim · Answer

ok. What about the angle? correct one is 24 degrees E of S.

turingtest · Answer

You need the components of your vector for the way I know how to do it, but I apparently made a mistake earlier...

istim · Answer

Ok. I'll try some method. If I have a problem. I'll ask again. Thanks for the help.

turingtest · Answer
