(a)
To Find: The
(a)
Answer to Problem 10PS
The magnitude of the vector
Explanation of Solution
Given:
The velocity of the skydiver falls at a constant downward velocity of
The breeze pushes the skydiver to the east at 40 miles per hour.
The given diagram is shown in Figure 1
Figure 1
Calculation:
As the skydiver falls down in the positive direction and horizontally east in the positive direction
Thus, the magnitude of the vector
(b)

(c)
To Find: The magnitude of
(c)
Answer to Problem 10PS
The sum is
Explanation of Solution
From the given figure the sum
Consider the magnitude of the above sum is,
Thus, the sum is
(d)
To Find: The angle to the ground that is the path of the skydiver when affected by the 40 mile per hour wind from due west.
(d)
Answer to Problem 10PS
The required angle is
Explanation of Solution
Given:
The speed of the wind is 40 miles per hour.
Calculation:
The required Figure is shown in Figure 2
Figure 2
Then, angle
(e)
To Find: The Figure that gives the visual representation of the problem and find the skydiver’s new velocity.
(e)
Answer to Problem 10PS
The required speed is
Explanation of Solution
Given:
The constant downward velocity of the skydiver is 120 miles per hour and the speed to the west is 30 miles per hour.
Calculation:
The required diagram is shown in Figure3
Figure 3
Consider the magnitude of the speed is,
