Question

A rectangular block of mass 30 kg measures 0.1 m by 0.4 m by 1.5 m.

A) Calculate the weight of the block.​

Answer 1

We have
`m=30\mathrm{kg}` and
`g\approx10\mathrm{(m)/(s^2)}`.

Calculate force (weight) by using
`F=mg`.

`F=mg=30\mathrm{kg}\cdot10\mathrm{(m)/(s^2)}=300\mathrm{N}`

Hope this helps.

Answer 2

294.30N

Step-by-step explanation:

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

`W=mg............(1)`

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

`W=30*9.81\\W=294.3N`
