Two people are pulling a boat through the water as in Figure P4.20. Each exerts a force of 600 N directed at a θ = 45.0° angle relative to the forward motion of the boat. If the boat moves with constant velocity, find the resistive force vector F exerted by the water on the boat.

  1. Well the force in the direction of motion each pulls with it 600cos45
    so the pulling force is 2*600*cos45.
    If the boat is not accelerating, the friction force should be equal to that.
