Question

Lf you exert a net force of 8 N on a 2-kg object, what will its acceleration be? a. 2 m/s2 b. 10 m/s2 c. 16 m/s2 d. 4 m/s2

Answer 1

D) a = 4m/s2

Step-by-step explanation:

`f = ma \\ a = (f)/(m) \\ a = (8)/(2) \\ a = 4`

where f = 8N and mass = 2kg

Answer 2

If you exert a net force of 8 N on a 2-kg object, the acceleration of the object would be
`4 m / s^(2)`.

Answer: Option D

Explanation:

According to Newton second law, it states the relation between mass and the force required to accelerate the object. The mathematical expression can be given as follows,

`\text {Force}=\text {mass} * \text {accelaration}`

The above expression shows that exerted force is equal to the product of mass and acceleration.

Where, in the given problem given the data as,

Force, F= 8 N

Mass, m = 2 kg

So, we can write the above equation as,

`\text {Acceleration, } a=(F)/(m)`

By substituting the given values in the above equation, we get,

`\text {acceleration, } a=(8)/(2)=4 \mathrm{m} / \mathrm{s}^(2)`

Therefore, the acceleration of the object would be
`4 m / s^(2)`.
