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.

You can use the equation: final velocity = initial velocity + acceleration * time. Rearrange the equation to solve for initial velocity: initial velocity = final velocity - acceleration * time. Simply substitute the given values for final velocity, acceleration, and time into the equation to find the initial velocity.

∙ 15y agoIf you know the initial and final velocity you can determine the acceleration (Velocity final- Velocity initial)/time = acceleration This can also be seen by integrating the acceleration. In this case lets assume acceleration is constant, then: acceleration=C Integration from time=initial to time=final gives C*(time final-time initial)=velocity final-velocity initial This integration scheme can also work if acceleration is not constant. In this case you must know how acceleration or velocity changes with time.

How do you find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
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 distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
How can you find final position without knowing initial velocity?
You can find the final position by using the acceleration and time. If you know the initial velocity and acceleration, you can calculate the final position using the kinematic equation ( x = x_0 + v_0t + \frac{1}{2}at^2 ), where ( x_0 ) is the initial position, ( v_0 ) is the initial velocity, ( a ) is the acceleration, ( t ) is the time, and ( x ) is the final position.
How do you find the final velocity without the initial velocity?
You can find the final velocity without knowing the initial velocity by using other variables such as acceleration and time. You can use the equation v = u + at, where v is the final velocity, u is the initial velocity (which is unknown), a is the acceleration, and t is the time.
When calculating acceleration to find the change in velocity you subtract the what velocity from the final velocity?
When calculating acceleration to find the change in velocity, you subtract the initial velocity from the final velocity. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time.
To find acceleration you subtract what?
To find acceleration, you subtract the initial velocity from the final velocity and then divide by the time taken to achieve the change in velocity. The formula for acceleration is (final velocity - initial velocity) / time.
What information do you need in order to find a object's acceleration?
To find an object's acceleration, you need its initial velocity, final velocity, and the time it takes to change from the initial velocity to the final velocity. The formula for acceleration is (final velocity - initial velocity) / time elapsed.
What is the formula for calculating final velocity when you know the initial speed and the acceleration?
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
How do you find final Velocity of an object?
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
How do you find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
How do you find final and initial velocity?
To find the final velocity of an object, you can use the kinematic equation: final velocity = initial velocity + (acceleration * time). If acceleration is constant, you can also use the equation: final velocity = initial velocity + (2 * acceleration * distance). The initial velocity can be found by measuring the velocity of the object at the beginning of its motion using a speedometer or other measuring device.
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
How do you find the final velocity given only distancetimeand initial velocity?
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
How do you find a final velocity without distance but given time?
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
How do you find final and initial velocities with the average velocity?
You can't.You only know what half the sum of (initial + final) is, (it's the average), but you don't know what the initial and final are.
How do you find distance with uniform velocity time final velocity and initial velocity?
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
