Question

A gust of wind blows an apple from a tree.
As the apple falls, the force of gravity on the
apple is 9.22 N downward, and the force of
the wind on the apple is 1.94 N to the right.
What is the magnitude of the net external
force on the apple?
Answer in units of N

Answer 1

The net external force on the apple

$$F=\sqrt{F_1^2+F_2^2}=\sqrt{9.22^2+1.94^2}=9.42\:\rm N$$
