A hovercraft prototype is tested while secured by a horizontal tether.
A forward fan produces a horizontal thrust of 48 N due north.
A second fan produces a horizontal thrust of 32 N in a direction 50∘50^{\circ}50∘ east of north.
The tether holds the hovercraft stationary.
Draw a scale vector diagram and use it to determine the magnitude of the combined thrust produced by the two fans.
Use your diagram to determine how far east of north the combined thrust acts.
State the force exerted by the tether on the hovercraft, including its magnitude and compass direction.
Explain how the orientation of the second fan makes the combined thrust greater than 48 N.
