Answer:
The mass of an object is 0.6122 Kg
Explanation:
Given:
Acceleration = 9.8 m/s
Force = 58.8 N
To Find:
Mass of an object = ?
Solution:
We know that according to newtons 2nd law
Force is the product of the mass and acceleration
F= ma
where
F = Force
m = mass
a = Acceleration
Substituting the values,
58.8 = m X 9.8
m = 0.6122 kg
