On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts a 8420-n force on the plane, directed upward at an angle of 69.0° above the horizontal. the plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction. (a) what is the weight of the plane? n (b) what is its horizontal acceleration?
