A stone, dropped from rest falls half of it's total path in the last second before it hits the ground. From what height was it dropped?
Gotta love past paper questions of A-Level Physics xD
Have fun ;)

I will do this within half a second of having a car hit me and dodge it like a boss.
I really do not care. |

oh i get it, there's no grammar used so it was confusing
this is what it should be:
A stone, dropped from rest, falls half of its**** total path in the last second before it hits the ground. From what height was it dropped? |

actually everything falls to earth at 9.81ms^-2 but thats okay sir.
and you're tryna be like "ohey, it fell half of it's distance in one second meaning another half of it's distance in another second so thats means it's initial velocity * 2"
here are some formulas to use:
s = ut + 1/2(at^2) v = u + at v = s/t s = ([u+v] / 2) * t t = [v - u] / a v^2 - u^2 = 2as
also remember suvat or:
s u v a t
Haha this is funny.

I quote: " g = - 9.8 m/s2 (surface of the Earth)"

"speed is m/s"
Shame that it's acceleration due to gravity and not speed due to gravity huh? (hint: the keyword is acceleration)

you: "you should know everything falls to earth at 9.82 m/s" me: "g = 9.82ms^-2" you: "yes thats gravity. i said speed."
"everything falls to earth" IS GRAVITY

I can tell by your sarcastic undertones, rude statements and sheer lack of common decency, that you and I could be best friends :)) |
