Zombie Bob has a body temperature of 68 ◦ F. At 3:30 pm, you place ZombieBob into a freezer that has a constant temperature of 10◦F. At 3:40 pm you measure Zombie Bob’s temperature and find it to be 60◦F. At what time will Z-Bob (your nickname for Bob) have a body temp of 15◦F?  Using the differential equation:  y' = k(M - y(t)) where k is a constant greater than zero, y(t) is the objects tenperature at time t, and M is the surrounding temperature of the object.

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.
