Two tug boats push on a barge in a bay with mass 61,014kg as seen in the
picture below. If one barge pushes east with a force of F1 = 50,597N, one
pushes north with a force of F2 = 32,351N and the third pushes at an angle of
35 degrees above the horizontal with a force of 12,000N. Find the resulting
acceleration of the boat
