A boat with a mass of 500kg is initially moving at a speed of 20m/s east (+). The kinetic friction force between the hull of the boat and the water has a coefficient of kinetic friction of m=0.05?

Part A) What is the magnitude and direction of the kinetic frictional force acting on the boat?

Part B) Oars are then extended and used so that the oars provide a force, F= 503N, in a direction that is 20° south of east. A steady wind pushes the boat at 35° north of east with a constant force, F=300N. What is the net force acting on the boat? (be sure to give magnitude and direction, and to include the kinetic frictional force from part A!)?

Part C) What is the acceleration of the boat? If you assume the acceleration is constant, what is the boat's velocity 2 seconds later?
