If Kofi is standing on top of a hill on a windy day holding a large, flat board perpendicular to the ground, and Sunita is standing at the bottom of the hill looking up at Kofi, how will the wind affect Kofi's stance, and what will Sunita likely observe about the board if the wind suddenly gusts stronger?

Provide a very brief response.
The wind will exert a force on the board Kofi is holding because the board presents a large surface area for the wind to push against. Since Kofi is holding the board perpendicular to the ground, the wind will likely push him backwards, making it harder for him to maintain his stance. If the wind gusts stronger, the increased force may cause Kofi to lose balance and move, or even stumble, backwards.

From her vantage point, Sunita will observe the board being pushed towards Kofi as the wind applies pressure on the board's surface. If the wind is strong enough and Kofi is unable to withstand the force, Sunita might see the board tilt or Kofi reposition himself to resist the wind, or potentially see him stumble if he fails to maintain his balance against the gust.
