Respuesta :
Well one pound is four and a half newtons. But we also have Earths gravity that we could use instead. 10 m/s^3 < Multiply that by 4 and you should end up getting roughly around 40 newtons.
Answer:
39.2 N
Explanation:
The weight of the bar in Newton's is given by
[tex]W=mg[/tex]
where m is the mass of the bar and [tex]g=9.8 m/s^2[/tex] is the acceleration due to gravity.
In this problem, the mass of the bar is m=4 kg, therefore its weight in Newtons is
[tex]W=mg=(4 kg)(9.8 m/s^2)=39.2 N[/tex]
