You cannot find the initial velocity from an acceleration-time graph on its own. What you can do is find the change in velocity over the first T units of time. This is the area under the a-t graph from t = 0 to t = T. This may be a simple calculation of the area of a rectangle or a trapezium or may require integration. But, like all integrations, you end up with an unknown constant - in this case the initial velocity. You must have some additional information - usually a boundary condition - that allows you to find this constant and so the initial velocity.

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 acceleration with velocity given?
Use the formula Acceleration = (final velosity - initial velocity)/ time.
How do you find initial acceleration.?
You use the information you're given, along with the equations and formulas you know that relate distance, time, speed, and acceleration, to calculate the number you're asked to find. And here's a tip: Chances are that the initial acceleration, the final acceleration, and the acceleration all along the way, are all the same number.
When calculating acceleration to find the change in velocity do you subtract the initial velocity from the final velocity?
Yes.
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 the time acquired by initial velocity in an acceleration -time graph?
To find the time taken to acquire a certain velocity in an acceleration-time graph, locate the point on the graph where the velocity reaches the desired value. Then, find the corresponding time on the horizontal axis at that point. This time value represents the time taken to acquire the initial 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.
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.
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 recognize acceleration on a graph?
Average Acceleration can be verbally defined as the change in velocity in a certain change in time... More simply put: Average Acceleration = (Final Velocity - Initial Velocity) / (Final Time - Initial 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.
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 make an acceleration time graph from the data of a velocity time graph?
To create an acceleration-time graph from a velocity-time graph, you need to find the slope of the velocity-time graph at each point. The slope represents the acceleration at that specific instant. Plot these acceleration values against time to get the acceleration-time graph.
How do you find acceleration with velocity given?
Use the formula Acceleration = (final velosity - initial velocity)/ time.
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.
