ANSWER
C. [tex]F=4.5 \times10^3[/tex]. newtons
EXPLANATION
According to Newton's second law,
[tex]F_{net}=ma[/tex], where
[tex]m=1.00\times 10^3kg[/tex] is the mass measured in kilograms.
and
[tex]a=4.5ms^{2}[/tex] is the acceleration in metres per second square.
We substitute these values to obtain,
[tex]F=1.00\times10^3 \times 4.5[/tex].
We rearrange to get,
[tex]F=1.00\times4.5 \times10^3[/tex].
We multiply out the first two numbers and leave our answer in standard form to get,
[tex]F=4.5 \times10^3 N[/tex].
The correct answer is C
