Well, I am having trouble doing a big project that's due this monday. I can't get any of my formulas to work, and I so I used logic on a motion problem.
Here's my made up problem that I have to graph in Excel:
An object travels at 39m/s for 4 seconds and then slows down at a rate of -6m/s² for 6 seconds.
(Sorry the columns aren't that well aligned, I had to copy it from Excel)
Time, sec \ Position, m \ Velocity, m/s \ Acceleration, m/s2
0 ----------- 0 ----------- 0 ----------- 0
1 ----------- 39 ----------- 39 ----------- 0
2 ----------- 78 ----------- 39 ----------- 0
3 ----------- 117 ----------- 39 ----------- 0
4 ----------- 156 ----------- 39 ----------- 0
5 ----------- 189 ----------- 33 ----------- -6
6 ----------- 216 ----------- 27 ----------- -6
7 ----------- 237 ----------- 21 ----------- -6
8 ----------- 252 ----------- 15 ----------- -6
9 ----------- 261 ----------- 9 ----------- -6
10 ----------- 264 ----------- 3 ----------- -6
So... I don't know any of the positions for sure after 4 seconds, or any of the velocities after 4 seconds. I just kind of used logic, it's pretty easy to follow what I did to find the positions and the velocities from 5-10 seconds. Are these right?
I can't get something that seems right when using my forumlas... can you give me some forumals to find the position and the velocities?
(oh, and after reading this forums FAQ, Yes I have spent lots of hours on this project, and have gotten help from both my brother and dad, but I am not going to see them again before this project is due, so I really need some help)
THANKS A LOT!
