Two boats push on a barge at different angles. The first boat exerts a force of 6.9 x 105 N in the x-direction, and the second tugboat exerts a force of 4.7 x 105 N in the y-direction. The mass of the barge is 7.0 × 106 kg and its acceleration is observed to be 7 x 10−2 m/s2 in the direction shown. What is the drag force of the water on the barge resisting the motion? What is the Resultant Angle?
