Which subfield of physics would you say is involved in the explanation of rainbows based on the brief descriptions provided in the given table? Which subfield is involved in describing the fall of an acorn? Explain.

Range of a projectile It is known from physics that the range $R$ of a projectile is directly proportional to the square of its velocity $v$.

Express $R$ as a function of $v$ by means of a formula that involves a constant of proportionality $k$.
