Remember when you see those two signs next to each other its “kao” which is keep add opposite so for b its 6-(-3) but you do keep add opposite so now it’s 6+3=9. for c it’s -2-(-5) and we still do kao which now it’s -2+5 different signs you subtract so now it’s 3 we always keep the sign of the higher variable and 5 is positive so the answer is positive.

When a force of 30 N acts on a certain object the acceleration of the object is 5m/s2 if the force is changed to 54 N what will
PtichkaEL [24]

Answer:

The correct answer is 9 m per second^{2}

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}

∴ 30 = m × 5

⇒ m = 6.

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

∴ 54 = m × x

⇒ x = \frac{54}{6} = 9

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