Np ^^

lol i am allowed , otherwise it would've not let me but yeh it was big in height wise so it looked GAY :)

I'v done inequalities , harder app of 2 unit maths , circle geometry and just finished The linear function which i like :D:D lol what about all you guys that do ext maths ?

yeh i wrote about instantaneous acceleration

Lol do you want me to put it back ? :D

Hey . I'll try to help , this question is really confusing... because the rocket is moving 1000m/s then like it fires out rockets and we don't know what speed those rockets are going at. Hmm , i'll tell you my attempt , but srsly this question is hard :D r = ut + 1/2at^2 r = 240 km =...

it's different for average Acceleration it's a = v-u/t in words... acceleration is equal to change in velocity over change in time. v is final velocity u is initial velocity a = 7-8/2 -1 = -1 m/s/s towards somethings.. like north or u can removes the - and change the direction to...

customize profile :)

Love your sig it's soo cute

Lol my teacher said do the hard sub first , cuz it will eff u up LMAO so learn it well, we're doing waves now i kinda learnt it already and i'v kinda learnt the electricity one in the long holidays it would be instantaneous , because it's the velocity at 2 seconds

No problem :)

the ball accelerates vertically upwards to the air lOL at 9.8 m/s/s

Lol i'v done this topic first it's A lot of maths trust me , many formulas but you'll like it I'm used to it now your pretty smart , knowing that your using year 10 knowledge :)

You did + 9.8 the formula is r = ut = 1/2at^2 r = 16 x 2 + 1/2 x - 9.8 x 2^2 r = 12.4 m

constant acceleration of gravity He probably wrote the first part , then instead of writing , The ball accelerates at (constant) 9.8 m/s/s towards blah blah blah . He just put it in brackets

toast , apple pie , water , chocolate oak lOL i DIDn't eat lunch oh well can be my dinner

LOL yeah Know it's meant to retard Haha yeah just was about to edit it but u wrote it soo yep it's fine :D

I think u use v = u + at u(initial velocity) = 16 m/s a = -9.8 m/s/s (works against gravity and retards) t = 2 s v = 16 + -9.8(2) v= -3.6 m/s

yep , i had school today aswell

1am ? in holidays lol yeah not in school times ><
