What else can I help you with?
A equals vf-vi divided by t?
(vf-vi)/ t is ?
What is the equation for average acceleration?
A equals Vf minus Vi divided by time equals triangle v divided by time
What is final speed divided by acceleration?
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
How to solve vf vi plus at equation steps?
Well, let's break it down nice and easy. To solve the equation vf = vi + at, you first subtract vi from both sides to isolate vf. Then, you multiply a by t and add the result to vi to find vf. Remember, take your time and enjoy the process of solving equations like this - it's just like painting a happy little picture!
How is acceleration related to the distance and time elapsed?
acceleration cannot be calculated from these values alone unless one makes a few assumptions: Vf=final velocity Vi=initial velocity a=acceleration d=displacement t=time assume Vi=0 (Vf-Vi)/t=a Vf=at+Vi Vf**2=Vi**2+2ad (at)**2=2ad aatt=2ad att=2d a=2d/t**2

What is the equation for average acceleration?
A equals Vf minus Vi divided by time equals triangle v divided by time
What is the formula used to calculate the accelerating?
A=Vf-Vi/t Acceleration is the final velocity minus the initial velocity divided by the time it too to reach it
What is final speed divided by acceleration?
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
What is vi equals vf-at?
Yes recalling the first equation of motion ie Vf = Vi + at Here Vf is final velocity and Vi is the initial velocity. a the acceleration and t is the time Now taking at on the other side ie left side we get Vf - at = Vi This is what mentioned here.
How do you calculate beginning speed of an object?
The beginning speed of an object can be calculated using the equation: Vf = Vi + at where: Vf = final speed Vi = initial speed a = acceleration t = time You can rearrange the equation to solve for Vi: Vi = Vf - at

If the average speed of a car is 80mph and it started from rest what is its final speed?
Vavg = (Vi + Vf)/2 Vi = 0 Vavg = Vf/2 Vf = 2*Vavg Vavg = 80 Vf = 160
What is the relationship between work and motion?
1) Work input = Force * distance 2) Force = mass*acceleration 3) Acceleration = (Vf - Vi) ÷ time 4) Force = mass * [(Vf - Vi) ÷ time] 5) Distance = Average velocity * time 6) Average velocity = (Vf + Vi) ÷ 2 7) Distance = [(Vf + Vi) ÷ 2] * time Eq#4 * EQ #7 8) Work input = mass * [(Vf - Vi) ÷ time] * [(Vf + Vi) ÷ 2] * time Time cancels 9) Work input = mass * (Vf - Vi) * (Vf + Vi) ÷ 2 10)(Vf - Vi) * (Vf + Vi) = Vf^2 - Vi^2 11)Work input = mass * [Vf^2 - Vi^2] ÷ 2 12)Work input = mass *( Vf^2 ÷ 2) - mass * (Vi^2 ÷ 2) 13)Kinetic energy = ½ mass *velocity ^2 14) Change in KE = (½ mass * Vf ^2) - (½ mass * Vi ^2) Equation #12 = Equation #14 so 15)Work input = Change in KE 16)Work input = ∆ KE
