An object accelerates at 2.0 m/s2 when a force of 12 n is applied. what is the mass of the object?

6 kg

Explanation:

Using equation for Second Newton law:

F=ma

we can find mass of object:

m=F/a

F=12N

1 N= kg*m/s²

a=2.0 m/s²

m=12 N/2 m/s²

m=6 kg

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

unbalanced force
