Style sheet. These are the conventions used in this book. Vector quantities (F, g, v) are written in a bold, serif font — including vector quantities written with Greek symbols (α, τ, ω). Scalar quantities (m, K, t) and the magnitudes of vector quantities (F, g, v) are written in an italic, serif font — except for Greek symbols (α, τ ...

The equation above can be used to calculate the final velocity of an object if its initial velocity, acceleration and displacement are known. To do this, rearrange the equation to find v:
A famous problem involving projectile motion is the "monkey and hunter problem" (Fig. 12.8.1 12.8. 1). A hunter spots a monkey hanging from a tree branch, aims his rifle directly at the monkey, and fires. The monkey, hearing the shot, lets go of the branch at the same instant the hunter fires the rifle, hoping to escape by falling to the ground.
