Answer 1

Hello!

what is the net force of this object if it is 400 N up and 600 N down?

In this case, as the meanings of the vectors are opposite, one of the forces receives the negative signal and thus a piece of the other vector is drawn, as shown in the figure. And to know the module of the resultant force, if it subtracts the modules of the forces.

`F_(Net) = F_(grav) - F_(air)`

`F_(Net) = 600 - 400`

`\boxed{\boxed{F_(Net) = 200N}}\end{array}}\qquad\checkmark`

Answer:

200N
