Math Problem Statement
A ball is thrown straight upward with an initial velocity vi and in a time t reaches the top of its flight path, which is a displacement yf above the launch point. Consider that same ball being thrown upward with an initial velocity of 2 x vi x a. Determine the displacement of the top point above the launch path.
