True.
Why?
To know if the statement is true or false, we just need to use the following convertion factor:
[tex]1lb(force)=4.44N[/tex]
or
[tex]1N=0.22lbf[/tex]
Now, converting from pounds to Newtons, we have:
[tex]9lb*\frac{4.44N}{1lb}=39.96lb=40lb[/tex]
Hence, the statement is true.
Have a nice day!
