Review

We use the \(x\) and \(y\) axes to define the plane in which the projectile moves, with the positive \(x\) axis pointing in a horizontal direction and the positive \(y\) axis pointing vertically upward. Because the constant acceleration vector \(\vec{a}\) points vertically downward and has magnitude \(g\), the components of \(\vec{a}\) are:
