ohh lol, now i get it, thanks :D

(t - 0.5) for the first stone and t for the second stone, for that cas the time for the first one is 5 less than the time for the second stone. so is this correct "(t + 0.5) for the first stone and t for the second stone,"?

don't you mean "t for the first stone and (t "+" 0.5) for the second stone,"?

can you also do: d= -1/2(a)(t+.5)^2 cas the ffirst stone is .5 seconds in air longer than the second stone

so after you foil, you make the displacement equal to each other, and then solve for t, and then plug "T" into the original equation?

i still don't get the answer, can you explain the steps please

Homework Statement One stone is dropped from the the top of a tall cliff, and a second stone with the same mass is thrown vertically from the same cliff with a velocity of 10.0 m/s [down], 0.50seconds after the first. Calculate the distance below the top of the cliff at which the second...

thanks I see my mistake, umm if possible can you show me how to do this question? I still didn't take calculus, I just started Advance Functions, just finished first chapter

Hey Sudharaka, How did you get \[A_{s}=\frac{2(\pi r^3+350)}{r}\] and I didn't learn how to do the first derivative test or the second, can you show me, or tell me where I can learn how to do that? please and thanks

Ok, so I did a test today for advance functions and there was a question: the volume of a pop can is 350ml, find the minimum surface area and determine the dimensions. Where I got stuck:350=pi(r)^2*h h=350/pi(r)^2SA= 2pi(r)^2+2pi(r)( h) SA=...

The velocity of waves in a liquid depends on the wavelength λ, surface tension γ, and density ρ, of the liquid, Derive an equation to relate v, with wavelength, surface tension and density, (note: surface tension, has a formula of force per unlit length and SI unit of Nm^-1)

simplify and answer should be in positive exponents. (((4x^6)^3(4y^-8))/((2x)^4(12y^3)^2))^1/2 please help and thanks
