What acceleration would be the net force ?

What acceleration would be the net force of 84N produce on each of the following masses.



4.2 kg



I need to see how one is done, there are alot of questions but once I see the formula used once i will beable to do it on my own.What acceleration would be the net force ?
Just one formula and its all sorted.

F = ma



Since you need a,

take m on LHS

F/m = a

F = 84 N

m = 4.2 kg



a = F/m = 84 / 4.2 = 20 m/s虏
