Question

The force required to produce an acceleration of 3m/s² in a body of mass 6 kg is​

Answer 1

Answer:

Mass = 20g = 0.02 kg

a = 3 m/s2

F = ma

Thus, we have

F = 0.02 x 3 = 0.06N

please thanks my all answer and follow me

Answer 2

Answer:

The force required to produce an acceleration of 3m/s² in a body of mass 6 kg is​ $18 N$

Explanation:

According to Newton's second law of motion,

Force applied (F) will be the product of the mass of the object and its acceleration.

or in other words,

Let  'F' be the force required to produce an acceleration 'a' in a body of mass 'm' will be  

$F = ma$   ...(1)

In the question, it is given that,

$m = 6\ kg$

$a = 3\ m/s^{2}$

Substitute these values into equation(1),

$F = 6\times 3 = 18 N$
