Two tractor trailers, each (16 mathrm{~m}) long and (4.0 mathrm{~m}) tall, are parked next to each other

Question:

Two tractor trailers, each \(16 \mathrm{~m}\) long and \(4.0 \mathrm{~m}\) tall, are parked next to each other as shown in Figure P18.70. A light wind that is blowing at \(5.0 \mathrm{~m} / \mathrm{s}\) in the parking lot but at \(20 \mathrm{~m} / \mathrm{s}\) between the trailers causes the air pressure between them to drop. What is the magnitude of the force exerted by the air on each trailer? (Use \(1.0 \mathrm{~kg} / \mathrm{m}^{3}\) for the air mass density.)

Data from Figure P18.70
