what grade are you in
11th
ohh, bye i'm in 8th- sorry
I'll help you Jason.
the formula is a = F / m
Force (F) = 12 and Mass (m) = 144,
a = 12/144
a = 0.08
( A is Acceleration)
You're welcome!

thx but the awnser for me to choose from are:
A.
–12.0 meters/second2
B.
–3.3 meters/second2
C.
3.3 meters/second2
D.
10.3 meters/second2
A.
–12.0 meters/second2
B.
–3.3 meters/second2
C.
3.3 meters/second2
D.
10.3 meters/second2
I would say the answer is A because 144 is 12×12 or 12 squared (12^2)
thank tyou
You're welcome :)
