When a tornado passes near a building,there is a rapid drop in the outdoor pressure and the indoorpressure does not have time to change. The resulting differenceis capable of causing an outward pressure of 1.4on the walls and ceiling of the building. Estimate the tons of force exerted on a wall that is 8 feet high and 40 feet wide.

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
