Wind resistance is jointly proportional to velocity and surface area of the object. If an object is traveling 8 mph and has a surface area of 52 square feet it will experience a wind resistance of 93.6 Newtons. How fast must an object be moving to experience a wind resistance of 853.875 Newtons if it has a surface area of 69 square feet?? mph

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.
