Question: The figure shows two forces, F(vector) 1 = + 3000 N and F(vector) 2 = + 5000 N, acting on a spacecraft; the plus signs

The figure shows two forces, F(vector)₁= + 3000 N and F(vector)₂= + 5000 N, acting on a spacecraft; the plus signs indicate that the forces are directed along the +x axis. A third force F(vector)₃also acts on the spacecraft but is not shown in the drawing. Concepts:

(i) Suppose the spacecraft were stationary. What would be the direction of F(vector)₃?

(ii) When the spacecraft is moving at a constant velocity of 1850 m/s, what is the direction of F(vector)₃?

Calculations: Find the direction and magnitude of F(vector)₃?
