as seen from the side, a 3.74 kg box on a flat frictionless ground is pulled forward by a 4.20 n force at a 50.0 degree angle and pulled back by a 2.25 N force at a 122 degree angle. What is the acceleration of the box?
find the net HORIZONTAL forces acting on the box 4.20 cos 50 + 2.25 cos 122
then f = ma to find 'a'
