We have [tex]m=30\mathrm{kg}[/tex] and [tex]g\approx10\mathrm{\frac{m}{s^2}}[/tex].

Calculate force (weight) by using [tex]F=mg[/tex].

[tex]F=mg=30\mathrm{kg}\cdot10\mathrm{\frac{m}{s^2}}=300\mathrm{N}[/tex]

Hope this helps.

Answer:

294.30N

Explanation:

We use the following relationship to calculate the weight W of the block;

[tex]W=mg............(1)[/tex]

where m is its mass and g is acceleration due to gravity. The value of g is taken as [tex]9.81m/s^2[/tex], the mass of the object is given by m = 30kg. Hence;

[tex]W=30*9.81\\W=294.3N[/tex]
