Kedrick and Kaleb train by pushing a sled that weighs 300 kg at an acceleration of 2m/s^2. What force did they push the sled wit
stiks02 [169]

Answer:

\boxed {\tt 600 \ Newtons}

Explanation:

Force can be found by multiplying the mass and the acceleration.

F=m*a

The mass of the sled is 300 kilograms and the acceleration is 2 meters per second squared.

F= 300 \ kg * 2 \ m/s^2

Multiply.

F= 600 \ kg * m/s^2

1 kilogram-meter per second squared is equal to 1 Newton. Therefore, 600 kilograms-meter per second squared is equal to 600 Newtons.

F= 600 \ N

The force used on the sled is 600 Newtons.
