A throwing formula? I'm not really sure what you mean. I can tell you that t is usually time, v is usually velocity, and s could be a path length or position while h might be height. I think the first term, -16t^2, is wrong. If this is an expression for the height of an object thrown upwards with initial velocity v, then it should be h = s + vt - 4.9t^2, where s is the initial height (i.e., the height of the thrower), t is elapsed time, and -4.9 comes from the term 0.5*g*t^2, where g = -9.8 m/s^2, the acceleration due to gravity. That way, every term in the formula has dimensions of length.
