The correct answer would be to express large and small numbers.
Let <em>v</em> denote the initial speed of the ball. The ball's position at time <em>t</em> is given by the vector

where <em>g</em> is the acceleration due to gravity with magnitude 9.80 m/s^2.
The ball reaches the goal 13 m away at time <em>t</em> such that

at which point it attains a height of 2.44 m, so that



Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays.
