# i actually jumped backwards when i saw that!
very woo!

PS:
im needing help with my physics homework.....how do you work out acceleration on a speed/time graph? (with a straight line)

# acceleration
on a space hopper?

# it could be on a space hopper yes

i love spacehoppers

look very happy to be there, poor little mite.

I've heard there's a space hopper in these pics somewhere...

# isn't it
speed divided by time?
or something?

# ask and ye shall recieve
its the gradient of the graph.....gah, i can't believe i remember that

# er..
speed x time = distance.

here sums upthe entirety of my physics knowledge.

# The solution
Is the derivative, young grasshopper. Or the average slope between two points, for you non-calculus folk.

# so
it would be the lowest add the highest divided by the time?

# right
it starts at 0m/s and goes to 15m/s in 20 with a steady acceleration. how do i work it out?

# change in speed
divided by time.

15/20 = acceleration

# to help you
it's 0.75 m/s/s

# err, long time ago but
v=u+at
so a=(v-u)/t
final velocity- start velocity over time

# er...
If it's a straight line, all you need is the slope of that line. Rise over run. (y2-y1)/(x2-x1)=m=acceleration

# wouldn't you have to
work out the acceleration for each time segment and find the average of all those results?

# ooohhhh
i cant be arsed. ill get my brother to do it for me. i think he has a physics fetish or something
