Calculate the acceleration if you push with a 21 N horizontal force on a 2 kg block on a horizontal friction-free air table

Expert's answer

Let's use the Newton's law:

F = ma ==> a = F/m = 21[N]/2[kg] = 10.5[m/s²].

So, the acceleration is 10.5 m/s².

F = ma ==> a = F/m = 21[N]/2[kg] = 10.5[m/s²].

So, the acceleration is 10.5 m/s².
