Answer:
25.45kg
Explanation:
Mass is the quantity of matter in a body. It is a scalar quantity that is it has magnitude both no direction.
From newton's second law of motion which states that the rate of change of momentum of a body is proportional to the applied force which takes place in the direction of force applied.
This law gives a formula which relate force, mass and acceleration.
Force = mass x acceleration
Given that force = 56N , acceleration = 2.2m/s²
Since force(F)= mass(m) x acceleration(a)
Therefore F = ma
Divide both sides by a
F/a = ma/a
Therefore,
Mass(m) = F/a
Mass = 56N ➗ 2.2m/s²
Mass = 25.45kg
The S. I unit of mass is kilogram (kg).
Mass = 25.45kg.
