Homework Statement Hey guys, I was just wondering how do the beliefs of the Flat Earth Society defy against modern day physics? I'm doing a discussion board post for my physics class. I know they strictly do not believe in gravity but what else do they do against? For example about Newton's...

If it is already given then what is it? Oh is it 12.5 m/s?

Ok vertical velocity is 32.6 m/s...but how do i find the horizontal speed?

Homework Statement A rock is thrown horizontally from a bridge at a speed of 32.6 m/s. If the rock is 32.0 meters above the river at the moment of release, find how long the rock is in the air? 2.56 seconds. Find the horizontal distance to the point of impact from the point of release? 83.31...

Well yeah I don't have to be exact, I just some reasonable reasons why i did fluctuate. Now I just need to prove these reasons.

A motion detector.

Hey do you know a site where I can find where I learn how to break down vectors to their x- and y- components?
