Question

What is the force of an object that has a mass of 42 kg and an acceleration of 3 m/s22?

Answer 1

Answer:

$\boxed {\boxed {\sf 126 \ Newtons}}$

Explanation:

According to Newton's 2nd Law of Motion, force is the product of mass and acceleration.

$F=ma$

The mass is 42 kilograms and the acceleration is 3 meters per square second.

$m= 42 \ kg \\a= 3 \ m/s^2$

Substitute the values into the formula.

$F= 42 \ kg * 3 \ m.s^2$

Multiply.

$F= 126 \ kg*m/s^2$

• 1 kilogram meter per square second is equal to 1 Newton.
• The answer we calculated is equal to 126 Newtons.

$F= 126 \ N$

The object's force is 126 Newtons.
