#### Answer

10.19 $m/s^2$

#### Work Step by Step

To find the acceleration we need to find all the forces in the y direction. We are told the upward force produced by the engine is 2.6 x 10^5 N and we also know that the downward force of gravity is F = mg = (1.3 x 10^4 kg)(-9.81 $m/s^2$). Adding the two we get that the net Force is 2.6 x 10^5N - 127530N = 132470N. Since F = ma then a = 10.19 $m/s^2$
