The force of air resistance acts to oppose the motion of an object moving through the air. A ball is thrown upward and eventually returns to the ground.

The temperature of a substance during an experiment can be modeled by the function f (x) = - 7.5cos (πx30) + 31.4, where f (x) is the temperature °c and x is the number of minutes into the experiment.
