How to find an average acceleration using an average velocity?

[Cacti]

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.

Do I multiply average velocity by time?

Not if you are looking for something that has dimensions of acceleration.

 

[WWGD]

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.
