ummmm okay i shall try
its quite simple
thank you very much
oh thatThanks a lot applepie1996 could you do the (ii) part please
are you sure this is the question ?CHALLENGING QUESTION !!!
i think this question is GOING to come this year and i am 100 % sure !!
so any help ???
A ball is dropped froma height of 2m above a hard floor.
After each bounce , a ball rises to 3/4 of its previous height.
(a) how far has it travelled in total when strikes the ball for the nth term?
(b) show that the ball never travels more than 14 m in total .
i tried my best but never got it !
(a) ans is 14 - 16 * 0.75 ^n metre

does it really look like its mechanics ??Mechanics?
ya i am sure .... when u sum it up .. you get this exprssiomare you sure this is the question ?
maybe you are missing something
cause you can't just get 14 and 16 in the answer when the height is only 2m !
yeap
i think so
it looks mechanics-ish
ya i am sure .... when u sum it up .. you get this exprssiom
looks like its not mechanicsYea.. it seems so .. but if it were GP. The sum to infinity is 8 and not 14 and nth term would be 2(1-(3/4)^n)/(1-3/4).
2-2(0.75)^n/0.25
8-8(0.75)^n would be the answer.
i still cant get the head or tail of itlooks like its not mechanics
no wonder i couldn't get it
if i had my scanner working .... i would scan it .... i got a book ... and i am SURE it will come this year ... and saay i didnt tell u !!where is the question from?
LOL xDi still cant get the head or tail of it
its pure maths 1 ??if i had my scanner working .... i would scan it .... i got a book ... and i am SURE it will come this year ... and saay i didnt tell u !!
they dint -_-hmm i thought og giving accel and i think s1 is enough of a threat i wouldnt risk with s2 . hmm the other grades would have covered up i guess
