That's the formula for the height of an object that was tossed upward at a speed

of 40 meters per second, after ' t ' seconds .

This object has to be something like a canonball, or a Baseball pitched by a professional etc.

The initial vertical speed of 40 meters per second is almost 90 miles per hour upward !
