Question 3

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.

a.

Draw a scale vector diagram and use it to determine the magnitude of the combined thrust produced by the two fans.

[3]
b.

Use your diagram to determine how far east of north the combined thrust acts.

[1]
c.

State the force exerted by the tether on the hovercraft, including its magnitude and compass direction.

[2]
d.

Explain how the orientation of the second fan makes the combined thrust greater than 48 N.
