How to find an average acceleration using an average velocity?

Click For Summary
To find average acceleration using average velocity, it's essential to have the complete problem statement, as context is crucial for accurate calculations. The average velocity calculated was 1.146788991 m/s over 8.72 seconds, but without knowing the final velocity, the formula a_ave=(Vf-Vi)/(Tf-Ti) cannot be applied. Multiplying average velocity by time does not yield acceleration, as it results in distance. Instead, it may be more appropriate to consider the average velocity as (Vf - Vi)/2 if initial and final velocities are known. Providing the full problem statement will help clarify the necessary calculations for determining average acceleration.

Homework Statement
Calculate the average acceleration for each member over the first 10.0 m.
Relevant Equations
None given
I calculated the average velocity in a previous problem and got 1.146788991m/s over a time of 8.72s. I know I can’t use a_ave=(Vf-Vi)/(Tf-Ti) because I don’t know the final velocity and have no way to find it. Do I multiply average velocity by time?

Please post the full problem so that we can see what data you have available.

The full problem statement is necessary. For one thing, there is a difference between "average" over time versus "average" over distance.

Not if you are looking for something that has dimensions of acceleration.
 
Maybe average velocity= (Vf - Vi)/2?

The rule of the HW forum is that you post the full statement of the problem, not just snippets of it.

Thread 'Correct statement about size of wire to produce larger extension'

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
