The tugboat is connected to boat A, which has a mass of 300 kg and experiences a constant drag force of 50 N from the water. Boat A is connected via tow cable to boat B, which has a mass of 400 kg and experiences a drag force of 60 N. The tension in the cable between the tugboat and boat A is 2500 N. Find the acceleration of boat b (in m/s2).

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.
