Answer: F=ma
Explanation:
Among the given equations there is only one correct, we can know this with the dimension analysis of the units:
[tex]F=m.a[/tex]
This is the equation that represents Newton's second law, where the force [tex]F[/tex] has unit of Newtons ([tex]1N=1kg\frac{m}{s^{2}}[/tex]). In addition we have the mass ([tex]m[/tex]) in kilograms ([tex]kg[/tex]) and the acceleration ([tex]a[/tex]) in ([tex]m/s^{2}[/tex]).
