(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object is in free fall at the surface of the Earth. In a certain 1.0 second time interval, the average velocity of the object is measured to be 2.0 m/s downward.

What was the velocity of the object at the beginning of the 1.0 second interval?

2. Relevant equations

V_{avg}= v_{i}+ v_{f}/ 2

3. The attempt at a solution

I came across this as i am studying for my physics final.

The answer is 2.9 m/s upward.

I am not sure how to get this because i cannot think of the right equation to use to get me to the correct answer.

Any help or hints would be greatly appreciated. Thank you
