Q: Dorothy is up on her 15-m x 15-m roof enjoying the view of Kansas. Suddenly, a strong wind blows down her ladder, leaving her stranded. She knows that a high wind reduces the air pressure on the roof, and that there is a danger that the atmospheric pressure inside the house will blow the roof off. As the wind reaches a speed of 30 m/s, she calls to her Auntie Em for help. Calculate the force on the roof.
