only two forces act on an object (mass = 3.00 kg). 40.0N east and 60.0N north of east at 45 degrees. Find the magnitude and the direction (relative to the x axis) of the acceleration of the object.
I don't really know where to begin.

A 350-kg sailboat has an acceleration of 0.62m/s2 at an angle of 64 degress north of east. Find the magnitude and direction of the net force that acts on the sailboat.
I have f=ma to find the force.
F=350(0.62)
F=217N
Then I'm not...
