Answer :
Answer: The acceleration of 28 Kg object will be 2 [tex]m/s^{2}[/tex]
Explanation: Force acting on an object is defined as mass times acceleration acting on it.
Mathematically it is defined as:
Force = mass [tex]\times[/tex] acceleration
F = 8 [tex]\times[/tex] 7 = 56 N
If the same force is acting on a 28 Kg object then the acceleration of the object will be equals to force to mass ratio.
Acceleration = [tex]\frac{Force}{Mass} = \frac{56}{28}[/tex] = 2 [tex]m/s^{2}[/tex]
