Step-by-step explanation:
The expression of the applied force in terms of mass and acceleration by using Newton's second law is as follows;
F= ma
Here, m is the mass of the object and a is the acceleration of the object.
Calculate the acceleration of a 10 kg object acted upon with net force of 20 N in the above expression.
Put m= 10 kg and F= 20 N in the above expression.
20= (10)a
a= 2 m/s^2
Calculate the acceleration of a 18 kg object acted upon with net force of 20 N in the above expression.
Put m= 18 kg and F= 20 N.
20= (18)a
a= 1.11 m/s^2
Therefore, the acceleration of a 10 kg object acted upon with net force of 20 N is greater than the acceleration of a 18 kg object acted upon with net force of 20 N.
