Given information:
A skydiver is falling at a constant downward velocity of
Write the vectors
Calculation:
Magnitude of vector
Magnitude of vector
Hence,
b.
Use the figure to sketch
b.
Answer to Problem 9PS
Explanation of Solution
Given information: A skydiver is falling at a constant downward velocity of
Let
Use the figure to sketch
Calculation:
From the figure,
Hence, the result.
c.
Find the magnitude of
c.
Answer to Problem 9PS
The magnitude gives the actual rate of the skydiver’s fall.
Explanation of Solution
Given information:
A skydiver is falling at a constant downward velocity of
Find the magnitude of
Calculation:
Magnitude of
Hence, the effect of wind is negligible in the skydiver’s fall.
d.
Find angle to the ground.
d.
Answer to Problem 9PS
Explanation of Solution
Given information:
A skydiver is falling at a constant downward velocity of
If there were no wind, then the skydiver would fallin a path perpendicular to the ground. At what angle to the ground is the path of the skydiverwhen affected by
Calculation:
Consider the figure below,
The angle
Hence, angle to the ground is the path of the skydiverwhen affected by
e.
Draw a neat figure that gives a visual representation of the problem and find the skydiver’s new velocity.
e.
Answer to Problem 9PS
Explanation of Solution
Given information:
A skydiver is falling at a constant downward velocity of
The skydiver is blown to the west at
Calculation:
The diagram is given below,
The skydiver’s new velocity is
Magnitude of
Hence, the skydiver’s new velocity is
