Thanks heaps mate, i think I've figured her out, now i just have 4 momentum questions to go before i hand it into my teacher in 2 days time :/ (and its great to be here at PF ;) )

i don't know how to use the x^2 thing sorry :P , would the S = a negative number? because it can only travel downwards?

but in that case i have u = 14.7m/s s = 49m a = -9.8m/s^-2 i can't find an equation that will find the time?

i got an assignment for physics and my class hasn't done a lot of vertical motion yet, it sounds like a pretty traight forward question but I am battling. A helicopter is rising vertically with a velocity of 14.7m/s when its wheel drops off at a height of 49m i) calculate the time for the...
