Ok. Maybe I'm missing something here, but for part one, I thought free-fall acceleration would be 9.8 m/s^2. Of course, computer didn't take it, so is there a way to find it from the graph?

As for the second part of the question, I thought initial velocity is 0, but its not the right answer. :-(

I guess another way to find initial velocity would be take the derivative of x(t) when t = 0, but I don't know the equation for this problem.

Any insight is appreciated.
