Question

1. what is the momentum of a car with a mass of 2,000 kg moving at a constant velocity of 20 m/s? (1 point)

100 kg m/s
40,000 kg m/s
0.01 kg m/s
0 kg m/s

Explanation:

Step1: Recall the formula for momentum

The formula for momentum \( p \) is \( p = mv \), where \( m \) is the mass and \( v \) is the velocity.

Step2: Substitute the given values into the formula

Given \( m = 2000\ \text{kg} \) and \( v = 20\ \text{m/s} \), we substitute into \( p=mv \). So \( p=(2000)(20) \).

Step3: Calculate the value of momentum

\( (2000)(20)=40000\ \text{kg m/s} \).

Answer:

40,000 kg m/s
