Only two horizontal forces act on a 3.0 kg body. One force is 9.0N, acting due east, and the othr is 8N, acting 62 degrees north of west. What is the magnitude of the body's acceleration?(adsbygoogle = window.adsbygoogle || []).push({});

Fnet= ma ............so I took that to mean F1x + F2x = ma

F1x = 9 cos 0 = 9

f2x = 8 cos 62 = 3.76

a = (9 + 3.76)/3 = 4.25

The solution says 2.9
