Formula from Newton's 2nd Law: 
Force = mass*acceleration
3200 = 160*acceleration
3200 / 160 = acceleration = 20[tex]m/s^2[/tex]

To find the acceleration of the mass you'll need to use this formula;

a = [tex] \frac{F}{m} [/tex]

Now lets substitute and solve;

a = 3200 -N ÷ 160-kg
a = 20m/s²
hope that helps Have a nice day:D
