It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.

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 acceleration with velocity given?
Use the formula Acceleration = (final velosity - initial velocity)/ time.
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.
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
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.
To find acceleration you subtract what?
To find acceleration you subtract initial velocity from final velocity and divide it by time.
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?
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
How do you find final speed if acceleration time and beginning velocity is given?
(acceleration X time) + beginning velocity = final speed

Yes.
When calculating acceleration to find the change in velocity you subtract the what velocity from the final velocity?
You subtract the initial velocity from the final velocity and divide by the time interval.
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 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.
The equation used to find acceleration is what?
Average acceleration = final velocity - initial velocity/ final time - initial timeOr for short:Aave=Vf-Vi/Tf-TiHope that helps :)
How do you find final velocity given height and mass?
the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5
