Answer:
The greatest acceleration is presented in option A 60N & 2.0kg
Step-by-step explanation:
The second Newton's law relates the net force F exerted on an object of mass m and the acceleration it has by the equation:
F=m.a
The acceleration is found by solving the equation for a:

Let's compare the different options and choose the greatest acceleration.
A F= 60 N, m= 2 Kg.

B F= 1 N, m= 0.20 Kg.

C F= 5 N, m= 0.35 Kg.

D F= 12 N, m= 1 Kg.

The greatest acceleration is presented in option A 60N & 2.0kg
