## Homework Statement

I have this lab and my goal is to find how far I should place a box if I was to catch a plastic leprechaun that weighs 22.4 grams fired out of an air cannon. I did this lab and the final velocity I ended with was 12.76 meters/sec (29.72 meters was the average distance and 2.33 seconds was the average time)

Ignore air resistance.

## Homework Equations

d=v

_{i}t+(1/2)at

^{2}was ah equation I remember using while first doing projectile motion in class but because I cannot find my notes I am stumped.

## The Attempt at a Solution

d=?

v

_{i}=0m/s

t=2.33 sec

a=9.8 m/s

^{2}(gravity)

when I plugged all those values in the equation I gave I ended up with d=26.06 meters.

Now would this be right since my average distance was 29.72 meters?
