heres a question for u...(which i am unsure about)

Rikardo drops a tennis ball from 4.4 metres (supposing its a free falling object) how long will it take to hit the ground?

i used this equation,

d=ut+1/2*a*t^2

where d=4.4, u=0, a=9.8m/s^2.

i got 0.948s, can sumone verify this please?

richiee: its nice to be sure of your answers. by the HSC comes i hope you should be fairly confident. it comes throught practice. unfortunately theres no answers in the HSC to check against

how mad would it be if they supplied the answers (not the working of course) so you can know for sure if you got the answer

i guess heaps of people will take too long on questions since you would stay on it until you got the matching answer

but you shouldnt be running out of time in a physics exam in the first place...

 

[redslert]

not everyone is as smart as you Constip8edSkunk

But im saying if u got answers to all the questions heaps would stay on each question until the answers match
