When a 86.8 kg object is in free fall, it feels a force of 850.64 N. What is its acceleration?
I usually avoid physics questions but
1N=1kg m/s2
force=mass x acceleration
850.64=86.8*acceleration
acceleration=850.64/86.8
acceleration=9.8m/s2
Which means that the object was probably falling close to sea level on the planet Earth. (I think)
