Question

A hovercraft is being driven across a lake on a very windy day. The wind exerts a force of 5000 N north on the hovercraft. The propellers driving the hovercraft also exert a force.

What is the net force (to 3.s.f ) on the hovercraft when the force applied to the hovercraft by the propellers is: 10 000 N west

Answer 1

The net force on the hovercraft is 11200 N.

Step-by-step explanation:

Given;

force exerted on the hovercraft by wind, F₁ = 5000 N north

force exerted on the hovercraft by the propeller, F₂ = 10,000 N west

The net force on the hovercraft is calculated as;

`F_(net) = √(F_1^2 + F_2^2) \\\\F_(net) = √(5000^2 + 10,000^2) \\\\F_(net) = 11180.34 \ N\\\\F_(net) = 11200 \ N \ (3.s.f)`

Therefore, the net force on the hovercraft is 11200 N.
