Consider the following scenario. A pilot is steering a plane in the direction N 45° W at an air-speed (speed still in air) of 190 mi/h. A wind is blowing in the direction S 30° E at a speed of 32 mi/h. Set up the coordinate axes so that north is the positive y-direction and west is the negative x-direction. With respect to the still air, write a vector that represents the velocity of the plane and a vector that represents the velocity of the wind. V plane V wind Give a velocity vector of the plane relative to ground. (Round your values to three decimal places.) V = V plane + v wind Find |v|. (Round your answer to one decimal place.) |v| Find the true course and the ground speed (in mi/h) of the plane. (Round your answers to one decimal place.) true course N ground speed mi/h
