Concept
Recall the relation between force, mass, and acceleration.
F = ma
Where F is force, m is mass and a is acceleration.
Given
The 80 N force applies to an object and it gets 20 m/s² acceleration.
To find
We have to find the mass of an object.
Solution
Substitute the given values in the formula of force F = ma.
80 N = mass × 20 m/s²
mass = 80/20
mass = 4 kg
Hence the mass of the object is 4 kg.
