Knowing that a 0.90-kg object weighs 9.0 N , find the acceleration of a 0.90-kg stone in free fall . Express your answer to two significant figures and include the appropriate units.

Respuesta :

Answer:

The value of acceleration of a stone in free fall is [tex]10\ m/s^2[/tex].

Explanation:

Given that,

Mass of the object, m = 0.9 kg

Weight of the object, W = 9 N

We need to find the acceleration of a stone in free fall. The weight of an object is given by :

W = mg

g is the acceleration of the stone in free fall

So, [tex]g=\dfrac{W}{m}[/tex]

[tex]g=\dfrac{9\ N}{0.9\ kg}[/tex]

[tex]g=10\ m/s^2[/tex]

So, the value of acceleration of a stone in free fall is [tex]10\ m/s^2[/tex]. Hence, this is the required solution.
