Answer:
m
=
15
k
g
Explanation:
Force is given by Newton's second law as the product of an object's mass and acceleration,
→
F
=
m
→
a
.
We are given that
→
F
=
147
N
(downward), and we know that the acceleration of an object in free-fall is equal to
−
g
, or
−
9.8
m
s
2
. We can rearrange the equation for force to solve for mass.
⇒
m
=
(
F
a
)
=
−
147
N
−
