Answer:
500 Kg.
Explanation:
The problem is giving us the weight of the object the weight is different from the mass of an object
Weight is the mass of any object multiplied by gravity (the value of gravity is approximately [tex]9.8\frac{m}{s^2}[/tex] ).
The unit of weight are newtons that equals
[tex]N= Kg.\frac{m}{s^2}[/tex]
[tex]W= m.g[/tex]
we cleared the mass of the formula
[tex]W=m.g\\ m=\frac{W}{g} \\ m= \frac{4900N}{9.8 \frac{m}{s^2} }= 500 Kg[/tex]
