1. ### Calculate when displacement are equal

ohh lol, now i get it, thanks :D
2. ### Calculate when displacement are equal

(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,"?
3. ### Calculate when displacement are equal

don't you mean "t for the first stone and (t "+" 0.5) for the second stone,"?
4. ### Calculate when displacement are equal

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
5. ### Calculate when displacement are equal

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?
6. ### Calculate when displacement are equal

i still don't get the answer, can you explain the steps please
7. ### Calculate when displacement are equal

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...
8. ### Finding surface area with volume

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)^2 SA= 2pi(r)^2+2pi(r)(h) SA= 2pi(r)^2+2pi(r)(350/pi(r)^2)...
9. ### Dimensional analysis

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)
