a 4400 kg railcar speeds at 10 m/s towards the house. what is the momentum of the railcar? kg*m/s

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity.

Step2: Substitute given values

Given $m = 4400$ kg and $v=10$ m/s. So $p=4400\times10$.

Step3: Calculate the result

$p = 44000$ kg·m/s.

Answer:

44000
