Answer:
- The magnitude of the resulting force is 67 lbf.
Explanation:
Taking the east as the positive x direction, and the north as the positive y direction.
The first force points west, this is, in the direction of , so, is
For the second force, knowing the magnitude and directions relative to the x axis, we can find Cartesian representation of the vectors using the formula
where is the magnitude of the vector and θ the angle with the positive x direction.
So, the second force is
The net force will be :
To obtain the magnitude, we can use the Pythagorean Theorem
And this is the magnitude we are looking for.
