Question

What is the acceleration produced by a force of 12 newtons exerted on an object of 3 kg​

Answer 1

Given :-

• $\sf\red{Force \ exerted \ = \ 12 N}$
• $\sf\orange{Mass \ of \ object \ = \ 3 kg}$

To Find :-

• $\bf\green{Acceleration}$

Solution :-

Using Newton's second law of motion

$\star\:{\boxed{\sf{\purple{Force \ = \ Mass \ \times \ Acceleration}}}}$

$\to\:\:\sf{12 = 3 \times Acceleration}$

$\to\:\:\sf{\dfrac{12}{3} = Acceleration}$

$\to\:\:\sf{Acceleration = 4}$

$\star\:{\boxed{\sf{\blue{Acceleration\: produced\: by\: body \:= \:4 m/s^2}}}}$

Additional Information :-

• $\sf\red{Initial \ momentum \ = \ mu}$

• $\sf\orange{Final \ momentum \ = \ mv}$

• $\sf\purple{Change \ in \ momentum \ = \ mass \times (v-u)}$

Answer 2

Answer:

4 ms^-2

Explanation:

By Newton's Second Law of Motion,

Force = mass X acceleration

12 N = 3 kg X accn.

or, accn. = (12 kg ms^-2)/( 3 kg)

              = 4 ms^-2
