Answer:
The correct answer is 9 m per ![second^{2}](https://tex.z-dn.net/?f=second%5E%7B2%7D)
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 ![second^{2}](https://tex.z-dn.net/?f=second%5E%7B2%7D)
∴ 30 = m × 5
⇒ m = 6.
If the force is changed to 54 N, let the acceleration of the object be x m per
.
∴ 54 = m × x
⇒ x =
= 9
Thus when the force is 54 N, the acceleration of the object is 9 m per
.
