When a ball is thrown up into the air, it makes the shape of a parabola. The equation S= -16t^2 + v*t + k gives the height of the ball at any time, t in seconds, where âvâ is the initial velocity (speed) in ft/sec and âkâ is the initial height in feet (as if you were on top of a tower or building).

The equation S = -16t^2 + v*t + k describes the motion of a ball thrown up into the air. This parabolic motion is linear, meaning that at any second (t) the height of the ball is described by an equation with a constant rate of change. The equation takes into account the initial velocity (v) of the ball, as well as the initial position (k), and uses this information to calculate the displacement of the ball as each second passes. The sum of the negative 16t^2, the t*v, and the k can provide the exact height of the ball at any second (t).
