Answer:
The force parallel to the horizontal is 26.24 N
Explanation:
She pulls on the leash with a force F = 30 N, this force, since its at an angle of 29° (i will cal this angle
), it has a force component on x (the horizontal, i will call this force
) and a force component on y (the vertical, i will call this
).
This can be seen in the attached picture.
Since we are asked about the force parallel to the horizontal, we need to find the component of the force
, since
is the adjacent angle, we need to use cosine:

since
and 



The force parallel to the horizontal is 26.24 N
115.35 ft
Set the proportion up 37.50/105.50 = 41/x and solve for x
U=RI Ohm's law
then R=U/I
=120/0.08
=2250Ω
hope this helps you
Both magnitude and DIRECTION
