How would (a) an updraft affect a skydiver in reaching terminal velocity? (b) a downdraft?

(a)

To determine
The effect of an updraft to reach terminal velocity by the skydiver.

Explanation of Solution

In free fall the skydivers displace an amount of air equal to their mass to maintain a constant terminal velocity.

Drag force is required to push out the air from the path of skydiver. Updraft is rising of air upward. This is against the direction of gravity so this balance helps to attain the terminal velocity...

(b)

To determine
The effect of an updraft to reach terminal velocity by the skydiver
