Answer:

The correct answer is 9 m per [tex]second^{2}[/tex]

Step-by-step explanation:

Force is defined by mass of an object times it's acceleration.

Let the mass of the object be m kilograms.

When a force of 30 N acts on a certain object the acceleration of the object is 5 m per [tex]second^{2}[/tex]

∴ 30 = m × 5

⇒ m = 6.

If the force is changed to 54 N, let the acceleration of the object be x  m per [tex]second^{2}[/tex].

∴ 54 = m × x

⇒ x = [tex]\frac{54}{6}[/tex] = 9

Thus when the force is 54 N, the acceleration of the object is 9 m per [tex]second^{2}[/tex].
