a.
To find out which skydiver has greater terminal velocity
a.

Answer to Problem 67E
The skydiver which has cross-sectional area,
Explanation of Solution
Given information:
The terminal velocity
The table shows the terminal velocities for the various surface areas of a skydiver who weighs 165 pounds
Cross-sectional surface area, | Terminal Velocity, |
1 | 432.9 |
3 | 249.9 |
5 | 193.6 |
7 | 163.6 |
In the table the greater terminal velocity given is 432.9 so it is clear that cross-sectional surface area 1 has greater terminal velocity.
Therefore, the skydiver which has cross-sectional area,
b.
To describe how the different values of
b.

Answer to Problem 67E
The skydiver who have lower area has much velocity and the skydiver which has higher area has less velocity.
Explanation of Solution
Given information:
The terminal velocity
The table shows the terminal velocities for the various surface areas of a skydiver who weighs 165 pounds
Cross-sectional surface area, | Terminal Velocity, |
1 | 432.9 |
3 | 249.9 |
5 | 193.6 |
7 | 163.6 |
The table should be consider to relate the position of falling skydiver to the different values of
Therefore, the skydiver who have lower area has much velocity and the skydiver which has higher area has less velocity.
