To calculation:
The magnitude and direction of the
a.
Answer to Problem 34PPS
The magnitude of the vector is about
Explanation of Solution
Given information:
Calculation:
The vectors formed by the starting point at the school and the terminal point at the end of the parade is
Now use the trigonometry to get the direction of the vector.
The parade started at the origin and terminated below the positive x-axis is quadrant fourth, the direction of the vector is the angle that is makes clockwise from the positive x-axis, which is
Therefore, the magnitude of the vector is about
b.
To calculation:
The sum of two vectors and determine the length.
b.
Answer to Problem 34PPS
The total distance of the parade is about the
Explanation of Solution
Given information:
Calculation:
Use the distance formula to get the length of each leg of the parade.
First get the length of the leg between
Next, find the length of the leg between
So, the total distance of the parade is about
