Answer:

F = 132N

Explanation:

Let the pulling force be F

Given the mass of the barrel is 12 Kg and The acceleration is 1.2 m/[tex]sec^2[/tex]

We know that Net Force = [tex]mass\times acceleration[/tex]

Now net force = F - mg

F - mg = ma

F = mg + ma

F = m(a+g) = [tex]12\times (1.2 +9.8)=132N[/tex]  

Note that there will be a downward force acting on the body which is equal to mg
