How long do you have to fast before you can consider your stomach "empty"? As in that the pills you take will not mix with any food?

Thanks!

P.S.

No question here, I just like to say the word "Bigfoot". Somehow it's better as a question, too. "Bigfoot?" Like you are spotting him, or he stepped on your toe. It always amazes me that more people don't ask about him. He is pretty famous, hard to dis-prove, yet UFOs get all the Answers time. Its injustice, I say.

Still, if there was a Bigfoot, I would have expected him to make an appearance on Oprah by now, probably wearing Ray Bans and a tailored (of COURSE!) Brooks Brothers suit. He would listen to his intro, glancing conspicuously at his gold Rolex...

"Listen, Oprah, baby, I have to get ready for Letterman in an hour, can we step this up? Really, my press release answered all these questions... no, I told you I won't be reading your Book Club Selection... I won't dignify that with a response, of COURSE I can read... I am SO out of here!"

does anyone know how to do this problem??

I have done the sketches, but I'm confused because it says to "show all work" and I can't really think of any way to do it accurately... I just guessed the general shapes of the graphs.

Please help if you have any idea!!

1. Imagine dropping a ball onto a hard floor so that it bounces straight up several times. Consider the time interval that the ball spends in contact with the floor to be of short duration but now zero.
a. sketch a position vs time graph for the motion for > 3 bounces. Assume that after each bounce the ball returns to a smaller maximum height. Take up to be the positive direction and the level of the floor to be zero height.
b. Directly below the graph from part (a) and using the same scale for the time axis, sketch a velocity vs time graph for the motion of the ball.
c. Directly below the graph for part (b) and using the same scale for the time axis, sketch an acceleration vs time graph for the motion of the ball.
