Answer:

F=F_(f)=1171.5 N

Step-by-step explanation:

We know that the sailboat has a uniform movement, therefore the total force, the engine, and the wind must be equal to the friction force.

F=F_(f)

$F=F_(f)=\sqrt{F^(2)_(engine)+F^(2)_(wind)}$

$F=F_(f)=\sqrt{900^(2)+750^(2)}$

F=F_(f)=1171.5 N

Therefore the friction force is 1171.5 N.

I hope it helps you!
