Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We’ll start by looking at motion itself. Then, we’ll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you’ll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Why don't we just do Time = Distance/Velocity, t=80/72 =1.1secs (and why was the Answer different)
My accelaration is 32.4
All i did is divide 72/2 =n then divide 80/n = 2.22 why yours is 2.18?
Why my answer is 2.22sec
The last part, to figure out time he used the formula Δt= Velocity Average ÷ Acceleration, I was surprised that this gives the same answer as using Displacement ÷ Velocity Average to figure out the Δt. But when you think about it, it makes sense that they both equate to the same answer when using the decimal places for each variable. This is because the final velocity divided by the acceleration tells you how long it takes to get up to that speed with respect to acceleration, same as when you divide the distance (displacement) by the average velocity. Pretty basic when you break it down 😀
Why didnt you just use the formula Vf^2 = Vi^2 +2a times delta X
Wow! 72 m per s is seriously fast, by the time my watch's second ticks once the flight wouldve travelled 72 m, hatsoff to the unit designed it to travel so fast. Now, why cant a small unit of it be made and then i could fly 72 m in a sec
I am mad what is this
I used this method :
d=0,5*v*t
80=0,5*72*t ——–> t=2,2222…..
v=a*t ——-> a=v/t
a=72/2,2
a=32,4
Is it right?
Its not accurate as many already said, to takeoff and landing the carrier must be moving to reduce the airplane velocity…
So, V0 is arround 50 km/h or 30 knots
T=S/Va
A=Vf/T
Why go through all that
6:56 Why isn't he using the FOIL method I'm confused.
suvat
Just want to point out none of these calculations account for drag, which is an extremely strong opposing force.
Wouldn't the initial velocity be greater than zero due to the speed of the carrier?
Did he just calculated the acceleration without time? WTF
1:15 If you want to be flying lmao
May I know where you got the specification of the F/A 18 Hornet?
The best part is the pilot drawing!
if you want to calculate km/h to m/s just divide by 3.6 simple.
I'm not sure if u know, but you can simply multiply km/h with 3,6 to get m/s an divide vise versa
so, what the result
<3 love this vid
to change from km/h to m/s you can multiply 260(5/18)=72.2
Vi itsnt 0,, Vi is =30 Knts….or aprox 50km/h… wrond data collection.
