What was the answer for the corresponding acceleration time graph for the given velocity time graph? I choice the one that looks like a graph of y = 1/x (which I think was D), but I think it was wrong, because the velocity time graph was way to steep for that (the integral for 1/x is lnx, which is pretty unsteep). So was there an option of an acceleration time graph with a constant straight line that had a negative gradient? Because if there was, then it was probably that one.
