Question by me: Projectile motion makes me want to projectile vomit? Physics Help please!!!?
A person standing at the edge of a seaside cliff kicks a stone over the edge with a speed of vi = 19 m/s. The cliff is h = 50 m above the water’s surface. How long does it take for the stone to fall to the water?

Best answer:

Answer by Sassafras
Since it isn’t directly states I’m assuming the stone is kicked horizontally and starts with the vertical component of velocity at 0. If this is the case then vi is irrelevant. The only thing you need is “h”.

Using the basic position equation
y-y0 = v0t – 0.5gt^2
v0 = 0
so
y-y0 = -0.5gt^2
-50 m = -0.5gt^2
t = sqrt (100 m/g)
t = sqrt (100 m/9.8 m/s^2)
t = 3.2 s

Question by : Phobia of Vomiting, In desperate need of help?
I have a severe fear of puking.
I have had it since i was about 5/6.
It used to make me feel sick in the evenings.
It got better until about the age of 12 when i started getting the fear really bad, having to take days of school, getting obsessive about washing my hands and being really causious of others who might not have washed their hands. I could not stand to be sat in a room (lesson) without easily being able to get out the door to reach a toilet in case i needed to puke. I used to stay up all night until about 6 am to ensure i would wake up and puke.
I then manage to calm it down before taking my GCSE’s and for the last 6 months i have had it under control, i was sleeping properly eating properly and it wasnt affecting me.
However, it now appears to have come back, and perhaps worse. I went to the hospital for my childrens outpatients appointment, and a child projectile vomited everywhere in the waiting room, this has now made me obsessive and makes me think im going to puke all the time, and at the moment it is 2:35 am and i am up ! and i have an exam tomorrow at 8:am !
i really really really badly need help. any suggestions?
i forgot to add* I stopped eating meat, fish, and stopped eating at resteraunts incase i would somehow get a bug. I wouldnt travel anywhere in car without my mum,incase i got travel sick, which is bad because i have to travel every weekend with my football and hockey team.

Sounds like you are bottle feeding. Stop it and put him on the breast.
Its cleaner and safer and better for him emotionally as well.

Question by : would vomiting help clear mucus?
i’m just getting over a sinus infection, with antibiotics and all, and i was wondering if i should induce vomiting to help clear out my throat of all the post nasal drip that isn’t being coughed up? my hopes is that not only would the projectile of the vomit help to evacuate the phlegm, but if nothing else the acids would help erode at the mucus. any tips or recommendations?

Best answer:

Answer by MzMick
I don’t think it will work because of the anatomy. The mucus and coughing is generated in the bronchi and trachea which is part of our breathing apparatus. Vomiting empties the stomach via the esophagus. The stomach acid damages the delicate membranes and would probably cause the production of more mucus. You would be better off to gargle lots of salt water and use saline nasal sprays to cut the phlegm and heal the throat. Also drink lots of fluids to thin the congestion.

Question by beachcutie03: 5 month old baby vomiting and diarrhea, please help me!?
For the past 5 days my 5 month old son has not been feeling well. He’s been vomiting after his bottles, I’m not talking spit up, real full out projectile vomiting. Then he started having blow out diarrhea several times a day. So yesterday on day 4 I took him to the Dr. The Ped. didn’t seem that concerned. He said he’ll get over it in 5 to 7 days from when it started and told me to give him Pedilyte between bottles. So all day yesterday I did that. When i gave him his bottles of formula I would only give him 2 and 3 oz. at a time. Well this morning I wake up to another blowout diarrhea diaper and had to give him a bath. I had just got him dressed and was settling into my bed w/him to give him some more Pedilyte and he threw up all over the place. I just don’t feel like this his a virus. It’s day 5 and I’m not seeing any improvement at all. What is going on????
