okay what is the height of the bottom of the cliff?
lets go over this together.
haha :O ok ya lets go over it.
you can almost see that 2 squared is 4, and 4 * 16 = 64
the equation states that h is the height of the coin t seconds after it is dropped. You are asked to find when it reaches the bottom. So what is the height of the bottom?
the cliff is 64 ft. right? lol cuz u said whats the height of the bottom of the cliff i think
yes, I know what I asked. So, answer me, what do you think the height of the bottom of the cliff is?
if I am 6 feet high, how high is the bottom of my feet from the ground?
ok uhmm blonde moment rite now how bout 16?
haha wow blonde moment
throw h=0 in and solve for t!
Yes!. so the moment the coin touches the bottom of the cliff, it is 0 feet high from the ground.
craig is trying to rush through it lol
so equate h to 0 and solve the equation, that is, 0 = -16t^2+64
ah! ok one moment keep typing watever ur typing.
or, 16 t^2 = 64. or t^2 = 4 or t = +2 or -2. Since time cannot be negative, t = +2. So it takes 2 seconds to reach the bottom.
OH!!!! ok ok
that makes sense! (: thx!! xD
okay great! you are welcome.
