## Finding mass of an object

1. The problem statement, all variables and given/known data
Δx = 82.9056 m ± 1m
a = 9.8 m/s/s ( its gravity object is in free fall)
v0 = .2424 m/s
v1 = 40.3106
t = 4.11

I need to find the mass of an object and i have lots of variables to play with but couldnt figure out :( .
2. Relevant equations

Ohh well this looks dumb.

a= f/m ( f = force of gravity since its in free fall)

3. The attempt at a solution

a= mg/m
and if i do this mass cancels out and i am left with a = g so plz help

thank you for helping
