Question

Find the acceleration produced by a force of 12N exerted on an object of mass 3kg.

Answer 1

[tex]F=ma ; F=12N, m=3kg So, 12=3a a=4m/s^{2} [/tex]

Answer 2

Answer: The acceleration is 4 $\bold{m/s^2}$

Given:

Force = 12 N

Mass = 3 kg

Solution:

According to newton’s second law, we get,

F = ma  

Where,  

F = Force needed to accelerate the body  

m = Mass

a = Acceleration

According to this law, when an object of certain mass are required to move, then an acceleration is applied on the body. When the object’s mass is higher, the force is also higher (required).  

$a=\frac{F}{m}$

On substituting the given value, we get,

$\Rightarrow a=\frac{12}{3}$

$\therefore a=4 \ m / s^{2}$
