The force exerted by the wind on the sails of a sailboat is 310 N north. The water exerts a force of 240 N east. If the boat (including its crew) has a mass of 330 kg, what are the magnitude and direction of its acceleration?

magnitude in m/s2
direction in ° north of east

Add the two forces vectorially. Set the resultant equal to M a, where a is the acceleration vector. Solve for a, remembering that it is a vector. I will be glad to critique your work.

Further help will be forthcoming when work is shown.
