in june 2004 wat formula did u use to find the velocity..i understand the part tht ur resolving ur finding the vertical component of velocity ryt
r u using the formula 2as=v2-u2 do u take u2 at 0
2as=v sin theta
but y do u take 2 theata??
nid404:
you don't need the derivation
s= v2 sin 2 / g

in octnov 2004 Q25 y cant it b the frequency cuz then v already noe the speed of sound n v cud jst simply devide..
lol i got Q33 when i read it 2wice
Thanks alot By the way
neno:
s= v2 sin 2 / g
v nvr used this formula so wat are the conditions tht u use it under
when thrs in angle or it requires more
is it used in projectiles also when u wana find the velocity ??

i believe thats because its a stationary wave
