1) 9.57 N
We have two forces applied on the apple:
- The force of gravity, in the downward direction:
W = 9.42 N
- The force exerted by the wind, in the horizontal direction (to the right):
Fw = 1.68 N
The two forces are perpendicular to each other, so we can find the magnitude of the net force by using Pythagorean's theorem.
Therefore, we have:
2)
The direction of the net external force, measured from the downward vertical, can be measured using the following formula:
where
is the force in the horizontal direction
is the force in the vertical direction
In this problem,
and so we find:
