Answer:
A) R = (200 i ^ + 100 j ^ + 30k ^) m
, B) L = 223.61 m
, C) R = 225.61 m
Explanation:
Part A
This is a vector summing exercise, let's take a Reference System where the z axis corresponds to the height (flights), the x axis is the East - West and the y axis corresponds to the North - South.
Let's write the displacements
Descending from the apartment
10 flights of 3 m each, the total descent is 30 m
Z = 30 k ^ m
Offset at street level
L1 = 0.2 i ^ km
L2 = 0.1 j ^ km
Let's reduce everything to the SI system
L1 = 0.2 * 1000 = 200 i ^ m
L2 = 100 j ^ m
The distance traveled is
R = (200 i ^ + 100 j ^ + 30k ^) m
Part B
The horizontal distance traveled can be found with the Pythagorean theorem for the coordinates in the plane
L² = x² + y²
L = √ (200² + 100²)
L = 223.61 m
Part C
The magnitude of travel, let's use the Pythagorean theorem for the sum
R² = x² + y² + z²
R = √ (30² + 200² + 100²)
R = 225.61 m
Umm... I think I saw this question somewhere else answered.... You should look for it.
Match each knee ligament with the correct label are:
1. Posterior Talofibular Ligament
2. Calcaneofibular Ligament
3. Anterior Talofibular Ligament
4. Deltoid Ligament
<h3>What is a ligament?</h3>
A ligament is a smaller fibrous tissue that connects bones to other bones, allowing them to be connected strongly but still allowing room to move and bend.
For example, the bones that connect at your elbow are held together by ligaments. They're similar to tendons but on a smaller scale.
Thus, this could be the answer.
