The average gravity on Earth is:
[tex]g=9.81\frac{m}{s^2}[/tex]
Since N represents Newtons and Newtons is a measurement of force we can use the following equation:
[tex]F=ma[/tex]
Where F is force, m is mass, and a is acceleration. In this case the acceleration is the gravity acting on the object. Therefore, F=50N, a=g=9.81m/s^2 and m is to be determined. And so:
[tex]F=ma\\\\F=mg\\\\50N=m(9.81\frac{m}{s^2} )\\\\\frac{50N}{9.81\frac{m}{s^2} } =m(\frac{9.81\frac{m}{s^2} }{9.81\frac{m}{s^2} } )\\5.0968kg=m\\\\m=5.1kg[/tex]
Therefore, the mass is approximately 5.1 kg.
