## Homework Statement

Alright we had a lab and we threw water balloons off the college's stadium to determine the height.In result the I got 9.2m from an average of 1.37sec using y=1/2gt^2

Okay, this is where i get confused to use the right equation to determine vertical velocity.

## Homework Equations

y=Yo+Vot+1/2at^2

## The Attempt at a Solution

I did v=u+(9.8m/s^2)(2.81) to find the velocity. Is that right?
