On take off, the combined action of the engines and wings of an airplane exerts a(n) 7767 N force on the plane,directed upward at an angle of 59.1 degrees above the horizontal. The plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction. The acceleration of gravity is 9.8 m/s^2. What is the weight of the plane? Answer in N.

What is the horizontal acceleration a? Answer in units of m/s^2.
