Explanation:
Note: I would like to point out that if the parachutist is in free-fall, her apparent weight is zero. But her true weight--her gravitational attraction experienced from the earth--is as follows.
We're asked to find the weight of an object, with its mass known.
This is pretty straightforward, and we use the equation
w
=
m
g
where
w
is the magnitude of the weight, in newtons,
N
m
is the mass, in
kg
(given as
75
kg
)
g
is the acceleration due to gravity,
9.81
m/s
2
Plugging in known values, we have
w
=
(
75
l
kg
)
(
9.81
l
m/s
2
)
=
740
kg
∙
m
s
2
=
740
N
rounded to
2
significant figures.
