1. The problem statement, all variables and given/known data On takeoff, the combined action of the air around the engines and wings of an airplane exerts a 7049N force on the plane directed upward at an angle of 58.7 above the horizontal. The plane rises with a constant velocity in the vertical direction while continuing to accelerate in the horizontal direction. The acceleration of gravity is 9.8m/s2. What is the weight of the plane? What is the horizontal acceleration of the plane? 2. Relevant equations Net force = ma 3. The attempt at a solution I determined the weight of the plane to be 6023N using newtons second law and because of the lack of the vertical acceleration it was rather simple. Now I cannot find the horizontal acceleration. I have the thrust pushing the plane forward (7049N) and the weight of the plane (6023N), but I am still stuck with two variables, my restrictive force and the acceleration. Is there something that I am missing when it comes to determining the restrictive force?
