Question

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

Answer 1

`\boxed {\boxed {\sf 126 \ Newtons}}`

Step-by-step 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.
