Question

How much force is required to accelerate a 4 kg object 3 m/s2?

Answer 1

Given :-

Mass of the object = 4 kg

Acceleration of the object = 3 m/s

To Find :-

The force required to accelerate the object.

Analysis :-

Here we are given with the mass and acceleration of the object.

In order to find the force substitute the given values in the questions such that force is equal to mass multiplied by the acceleration of the object.

Solution :-

We know that,

• f = Force
• a = Acceleration
• m = Mass

Using the formula,

$\underline{\boxed{\sf Force = Mass \times Acceleration}}$

Given that,

Mass (M) = 4 kg

Acceleration (a) = 3 m/s

Substituting their values,

⇒ f = ma

⇒ f = 4 × 3

⇒ f = 12 N

Therefore, the force required to accelerate the object is 12 N.

Answer 2

Answer:

Given :-

• A force is required to accelerate a 4 kg object of 3 m/s.

To Find :-

• What is the force required.

Formula Used :-

$\boxed{\bold{\large{F\: =\: ma}}}$

where,

• F = Force
• m = Mass
• a = Acceleration

Solution :-

Given :

• Mass of an object = 4 kg
• Acceleration of an object = 3 m/s

According to the question by using the formula we get,

⇒ F = ma

⇒ F = 4 × 3

➠ F = 12 N

$\therefore$ The force required to accelerate an object is 12 N .
