I have the answers, but I don't know how to get them.

The starting graph is a position-time graph of a basketball being thrown straight up into the air.

From that graph i have to find an acceleration-time graph, and a velocity-time graph.

Can someone explain to me the acceleration-time graph? why is it a constant negative line, if the graph of the position graph first goes up then down?

I think I understand how the velocity-time graph works with this.

My next question wants a graph of position vs. time, and a graph of velocity vs. time for an object moving with a constant negative acceleration.

again i have the answers, but I really don't know how to get to them.

thanks in advance for the explanations :)
