If a stone is tossed from the top of a 190 meter building, the height of the stone as a function of time is given by h(t) = -9.8t2 – 10t + 190, where t is in seconds, and height is in meters. After how many seconds will the stone hit the ground? Round to the nearest hundredth’s place; include units in your answer.

geekgirl1988, please review the previous question you asked regarding the application of the discriminant. I made an error which I corrected.

-9.8t^2 - 10t + 190 = 190 t(-9.8t-10) = 0 t=-10/9.8 Thus it will fall after 10/9.8 secs

I think i did a mistake...sorry!
anonymous
  • anonymous
ok

The equation you need to solve is -9.8t^2 - 10t + 190 = 0

would i use the quadratic formula?
anonymous
  • anonymous
yes

ok on while i solve the problem.
anonymous
  • anonymous
you know the formula right
anonymous
  • anonymous
yes. doing th problem right now. almost done. hold on.

After you do it, just tell me how old are you? So that I can help accordingly, or else i might miss something you may not know

i got x=-3.6 or x=2.6 for my answer. and i am 22.
anonymous
  • anonymous
Right, now the point is can time be negative?
anonymous
  • anonymous
would that answer be no. if so then the answer to the problem would be 2.6 seconds per meter so it would be 494 seconds. or am i wrong.
anonymous
  • anonymous
Yup you are right, btw how did you get that value 494?
anonymous
  • anonymous
2.6*190=494. should i not put that into the answer.
anonymous
  • anonymous
Nope, that doesn't mean anything!
anonymous
  • anonymous
The last part would be 2.667
