Okay people I think I got it:
T=√2*d/A
I've worked through the problem a couple time so I think I have got this.
When Vf or Vi = 0 you use the Scalar form of the equation.
Am I right here?
PS. Seriously thank you, you will probably see me back here. I'm taking Physics 30 & Math...
Vf = 0 m/s becuase the plane is stopped.
Should I be finding out what Vi is before find out the time? Ahhh you seem like you know what I need to do... A little hint here :redface:
Would you be able to tell me how you would go about figure out this question:
If the arresting device on an aircraft
carrier stops a plane in 150 m with
an acceleration of 15 m/s2, find
the time the plane takes to stop
Maybe I need to start somewhere? I do not understand the quadric...
okay - so that is the wrong step? Where do I go from here. I'm sorry I just need a bit more information. I'm missing the basics and a quick reminder will make it click!
If you could even give me a step by step on it, or even a website with some basics too.
No I'm not exactly sure what you mean by that.
I just checked the textbook and that is the right equation.
Here is the question I'm stuck on:
If the arresting device on an aircraft
carrier stops a plane in 150 m with
an acceleration of 15 m/s2, find
the time the plane takes to stop.
Here...
Homework Statement
A= Acceleration
Vf = Final Velocity
Vi = Initial Velocity
D= Displacement
T = Time
Homework Equations
D=Vf*T - 1/2*a*(t)2
Solve for T
The Attempt at a Solution
I need to solve for T: This is what I got as my attempt but it is so very wrong still...
