Answer:


\boxed {\boxed {\sf 2 \ Newtons}}

Step-by-step explanation:

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


F= m * a

The mass of the stone is 0.2 kilograms and the acceleration is 10.0 meters per square second.

  • m= 0.2 kg
  • a= 10.0 m/s²

Substitute the values into the formula.


F= 0.2 \ kg * 10.0 \ m/s^2

Multiply.


F=2 \ kg*m/s^2

Convert the units.

  • 1 kilogram meter per square second (kg*m/s²) is equal to 1 Newton (N)
  • Our answer of 2 kg*m/s² is equal to 2 N


F= 2 \ N

The force is 2 Newtons.
