How do you get Vf and Vi from a given velocity For example how to find Vf and Vi from 7 ms?

If the speed is 7 meters per second all the time, then you already have your initial and final speed. If the speed changes, you need additional information.

Formula for finding time?
if acceleration a, initial velocity vi and final velocity vf is given , then time could be found by applying formula t=vf-vi/aand if distance s and velocity v is given then t=s/v
How do you find acceleration when given time and change of distance and velocity?
vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a.vf = vi + at, where t is time time. Solve for a.
How do you find acceleration if only given a velocity?
If you have an initial and final velocity and time you can figure it out with this equation, Vf squared=Vi squared1/2a(t squared) If you don't have those you cannot find acceleration. However the acceleration on Earth is a constant -9.81
Formula for velocity?
V = d / t (or v = dd/dt & v = integral of acceleration with respect to time for physics involving calculus) where V is velocity, d is displacement (distance traveled) and t is time. vf = vi + a*t (vf)^2 = (vi)^2 + 2*a*d Where vf is final velocity, vi is initial velocity, and a is acceleration v = p/m Where p is object's momentum and m is object's mass
What is the formula of vertical velocity?
vf=vi+at or vf2=vi2+2ad where a=-9.8m/s2
What is the formula to find accelerate?
To find acceleration, it is the change in velocity over the change in time. (Vf-Vi)/t. where: Vf is final velocity, Vi is initial velocity, and t is the time interval.

A rocket ship leaves the earths atmosphere its initial velocity is less than its final velocity this is example of?
Final velocity vf is greater than the initial velocity vi . That is vf > vi . This is an example of acceleration (positive). Average acceleration aav = [vf - vi]/[tf - ti] where ti is initial time, and tf is final time.
How do you find Vf?
You use the information items you're given, which for example may include time, initial velocity, initial and/or final position, or acceleration, together with the equations you've learned that express the relationship among these quantities.
How do you find the initial velocity just with the accelaration final velocity and time?
To find acceleration, you take Vi [Initial Velocity] and you subtract if from Vf [Final Velocity.] (Vi - Vf) If they Vi and Vf are already given, you take the two givens and you subtract them from each other. Vi minus Vf. Do not do Vf minus Vi or it will be wrong. After you do that, you divide your answer from T [Time] (Vi - Vf) a= _____ t Once you get your answer, that will be your acceleration.
How do you find acceleration when given time and change of distance and velocity?
vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a.vf = vi + at, where t is time time. Solve for a.
How do you find change in velocity?
when using energy use the kinetic energy equation for change KE = .5(M)(Vf^2 - Vo^2) M = mass Vf = fianal velocity Vo = initial velocity
How do you find acceleration if only given a velocity?
If you have an initial and final velocity and time you can figure it out with this equation, Vf squared=Vi squared1/2a(t squared) If you don't have those you cannot find acceleration. However the acceleration on Earth is a constant -9.81
What is the process for getting the formula of final velocity?
Vf= Final Velocity Vo= Original Velocity a= Acceleration t= Time Vf=Vo+a(t)
How do you calculate initial velocity when given final velocity acceleration and time?
Acceleration is the rate of change of velocity per time, so to get velocity, multiply (acceleration)*(time). This will give the change in velocity over the specific amount of time. You must add the initial velocity to get the final velocity, so we have the formula: Vf = Vo + a*t, where Vo is the initial velocity. This means that you can rearrange to get Vo = Vf - a*t
What is the symbol for final velocity?
Vf
How do you find the time acquired by initial velocity in an acceleration -time graph?
t=(vf-vi)/a
