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

an object in free fall will accelerate at the same rate (g) regardless of its mass, so either the problem is missing some information, or the mass cannot be found based on the given information.
