Answer to Question #214905 in Physics for gigi

Question

1. An airplane is flying at a constant speed. The thrust from the propeller is 8 000 N [E]. A crosswind is applying a force of 2 000 N [N]. What is the net force acting on the airplane?

Answer 1

The net force is

$$F_\text{net}=\sqrt{8000^2+2000^2}=8246\text{ N}.$$

It is directed

$$\theta=\arctan\frac{ 8000}{2000}=76°$$

N of E.
