A wolf spider runs 75 cm west, then turns and runs 50 cm south. Which choice gives the correct solution for the resultant? Quest
1 answer:
The correct solution for the resultant of the wolf spider is:
R² = 75² + 50²
<h3>Resultant formula</h3>R² = (Displacement 1)² + (Displacement 2)²
Where
- R is the resultant displcaement
See attach photo for diagram
<h3>Data obatined from the question</h3>The following data were obtained from the question.
- Displacement 1 = 75 cm west
- Displacement 2 = 50 cm south
- Resultant dispalcement (R) =?
The solution for the resultant displacement of the wolf spider can be obtained as follow:
R² = (Displacement 1)² + (Displacement 2)²
R² = 75² + 50²
Thus, the correct answer to the question is:
R² = 75² + 50²

Here we can use the work energy theorem
here we know that
as it come to rest finally
now work done by friction force will be given as
Work done by spring force is given as
so now plug in all data above
so above is the friction coefficient
Answer:
The second vector points due West with a magnitude of 600N
Explanation:
The original vector points with a magnitude of 200N due east, the Resultant vector
points due west (that's how east/west direction can be interpreted, from east to west) with a magnitude of 400N. If we choose East as the positive direction and West as the negative one, we can write the following vectorial equation:
With the negative sign signifying that the vector points west.
