Answer:

Explanation:
The equation for the linear impulse is as follows:

where
is impulse,
is the force, and
is the change in time.
The force, according to Newton's second law:

and since 
the force will be:

replacing in the equation for impulse:

we see that
is canceled, so

And according to the problem
,
and the mass of the passenger is
. Thus:



the magnitude of the linear impulse experienced the passenger is 
Answer:
16 % and 9 %
Explanation:
Accurate reading = 10 N
reading of first balance = 8.4 N
reading of second balance = 9.1 N
Percentage difference in first reading
= 
=
= 16 %
Percentage difference in second reading
= 
=
= 9 %
