Explanation:

Answer 2

Hi,

Here is your answer

Given:

Weight of the body=420N

Acceleration due to gravity(g)=9.8m/s²

To Find:

Mass of the body

Solution:

Mass is given by the equation

Mass=Weight/g

Substituting the given datas, we get

Mass=420/9.8

Mass=42.86kg

Notes:

1.Mass is defined as the amount of matter an object has while weight is the force of gravity acting on an object.

2. The unit of mass is kg while that of weight is Newton.

Hope this helps you.
