Answer:
Explanation:
Force can be found by multiplying the mass and the acceleration.
The mass of the sled is 300 kilograms and the acceleration is 2 meters per second squared.
Multiply.
1 kilogram-meter per second squared is equal to 1 Newton. Therefore, 600 kilograms-meter per second squared is equal to 600 Newtons.
The force used on the sled is 600 Newtons.
