Physics

  1. A boat with a mass of 500kg is initially moving at a speed of20m/s east (+). The kinetic friction force between the hull of theboat and the water has a coefficient of kinetic friction ofm=0.05?

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

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

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