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 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.
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 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 initial velocity just with the accelaration final velocity and time?
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.

Yes.

A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
The final velocity can be calculated using the formula final velocity = initial velocity + (acceleration * time). Since the ball starts at rest, the initial velocity is 0. The final velocity = 0 + (acceleration * 5). To find the acceleration, you can use the formula acceleration = (final velocity - initial velocity) / time. The final velocity is unknown, but we just calculated the final velocity is equal to 5 times the acceleration, so acceleration = (final velocity - 0) / 5. Substituting the final velocity = 5 times the acceleration into the acceleration equation, we get acceleration = (5 * acceleration - 0)/5. Solving for acceleration, we get acceleration = 1 m/s^2. The final velocity is 5 m/s.
