Question

1. which has more momentum, a dog running after a ball at 3 m/s or a car parked on the street. (1 point) the car the dog they both have the same there is no way to tell

Explanation:

Step1: Recall momentum formula

Momentum $p = mv$, where $m$ is mass and $v$ is velocity.

Step2: Analyze the car's momentum

The car is parked, so its velocity $v_{car}=0$. Then $p_{car}=m_{car}\times0 = 0$.

Step3: Analyze the dog's momentum

The dog is running with a non - zero velocity $v_{dog}=3\ m/s$. So $p_{dog}=m_{dog}\times3>0$.

Answer:

B. the dog
