hey ppl.i have a doubt in physics?

Yes it is wrong.  It might be a good approximation for lower altitudes, but is not truly correct.  In the same way, Newton was wrong with his equations, but they still make good approximations over reasonable ranges of values.

I do not know you that well yet...............\n\n\nHow about a physics question or something challenging?

Horizontal momentum is conserved throughout the problem. i.e., when half the mass fell downwards, all of the horizontal momentum must be carried in the second.\nThere's too much missing information for me to go farther than that...

You're in luck.  I teach physics and I know exactly how to answer this question (it's based on the work-energy principle).  It's pretty simple, really.  But it would be best if we discussed it by messenger.  Yahoo Messenger me, my ID is\nfortitudinousskeptic\n\n- Kevin

Have you tried asking this question under the heading Science & Mathematics > Physics? You might have a better audience there.

I was a rock star in college physics!   Top of the class!  But I can't remember any of it now.  My teacher always said to start each solution by drawing a picture, then making a list of the varriable you know, and writing down the equations you thik you might need to solve.  It worked for me!\n\nPost your problem, maybe I can help.  Traditional physics problems have not changed much in the last 5 years, maybe I can remember.

I know the answer is in my basic physics book.  I would have to look it up.  You should too.

Bit confused, the question.

wtf why did you ask the same question as me?\n\nactually i was talking about fahrenheight as in temperature,so our questions are different, it's all good.

When V(t)=0 the particle stops.\nIt can have a(t)=0, but still moving (constant speed)

And you're asking this of physicists?????????????????

Not due to gravitational pull?!

there are some solved physics problems on \nhttp://www.dctech.com/physics/help/\nbut I don't know if it will help you out.

Read Newton's 3rd law of motion.\nAlso, use F=ma to figure out your acceleration.

I do not understand your questioin.. if it is a question

i dint get the question, can u elaborate a bit ?

The equations are wrongor insufficient. Post the correct data if you want me to help/ Alternately, you could also message me.
