A 2.7 kg mass accelerates at 7 m/s^2 in a(adsbygoogle = window.adsbygoogle || []).push({});

direction 28 degrees north of east. One of the two

forces acting on the mass has a magnitude of

12.6 N and is directed north.

Determine the magnitude of the second

force. Answer in units of N.

I did F2= sqr rt (ma^2+ F1^2)

= 22.715 N

This is apparently incorrect. This seems too easy and yet I cannot figure it out. I'm assuming F2 is in the positive "x" direction w/o a "y" component.

Any help appreciated.
