If you are referring to initial velocity with vi, then
Vfinal = Vinitial + a*t, where a is a constant acceleration, and t is the time.
So you must know a t and Vfinal to find Vinitial

Find the acceleration of a car that goes from A meters per second to B meters per second in 8 seconds?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Given the initial velocity (A), final velocity (B), and time (8 seconds), you can substitute the values into the formula to find the acceleration.
What is the mass of a rock if it produces a force of 147n?
To calculate the mass of the rock, you would need to know the acceleration due to gravity acting on it. Using the formula Force = mass * acceleration, you can rearrange it to find mass. Without the value of acceleration, we cannot determine the mass.
How do you find final speed if acceleration time and beginning velocity is given?
You can find the final speed by using the formula: final speed = initial velocity + (acceleration * time). Plug in the given values for initial velocity, acceleration, and time into the formula to calculate the final speed.

How do you find the minimum deceleration?
To find the minimum deceleration, you would need to calculate the change in velocity and time over which the deceleration occurs. Then, you can use the formula a = Δv / t, where a is the acceleration, Δv is the change in velocity, and t is the time. The minimum deceleration would be the smallest value calculated using this formula.
How do i find acceleration?
Acceleration can be found by dividing the change in velocity by the time it took to change. The formula for acceleration is acceleration = (final velocity - initial velocity) / time. Alternatively, acceleration can be found by using the equation acceleration = force / mass, according to Newton's second law of motion.
How do you find the acceleration of a pushed object?
You can find the acceleration of a pushed object by dividing the net force acting on the object by its mass, using the formula a = F/m, where a is the acceleration, F is the net force, and m is the mass of the object.
What is the correct formula manipulation to find acceleration when using the equation vf2 vi2 2ad?
To find acceleration using the equation vf^2 = vi^2 + 2ad, you can rearrange the formula to isolate 'a'. First, subtract vi^2 from both sides to get vf^2 - vi^2 = 2ad. Then, divide both sides by 2d to solve for acceleration: a = (vf^2 - vi^2) / (2d).
How do you find acceleration using mass and velocity?
You can find acceleration by using the formula: acceleration = (change in velocity) / (time taken) or a = (v2 - v1) / t. Once you have the acceleration, you can find the force using Newton's second law: force = mass x acceleration or F = m*a.
How do you find final speed if acceleration time and initial speed is given?
You can find the final speed using the formula: final speed = initial speed + (acceleration * time). Simply plug in the values for initial speed, acceleration, and time to calculate the final speed of the object.
What is the formula to find force when mass and acceleration are known?
The formula to find force when mass and acceleration are known is F = m * a, where F is the force, m is the mass, and a is the acceleration.
What would be the acceleration of recoil when a 60 kg person on roller blades pushes against a wall with a force of 30-n?
The acceleration of recoil can be calculated using Newton's second law, which states that force equals mass times acceleration (F = m*a). By rearranging the formula to solve for acceleration (a = F/m), we find that the acceleration of recoil in this scenario would be 0.5 m/s^2.
