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
yes i saw that radar and it is one solution.
I think i did a mistake...sorry!
The equation you need to solve is -9.8t^2 - 10t + 190 = 0
would i use the quadratic formula?
ok on while i solve the problem.
you know the formula right
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.
Right, now the point is can time be negative?
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.
Yup you are right, btw how did you get that value 494?
2.6*190=494. should i not put that into the answer.
Nope, that doesn't mean anything!
The last part would be 2.667
