Question

1. a 25 kg dog picks up a 1.7 kg bone and runs with it. if the dog is running at 6 meters per second, what is the momentum of the dog and the bone together?

Explanation:

Step1: Calculate total mass

The total mass $m$ is the sum of the dog's mass and the bone's mass. So $m = 25+ 1.7=26.7$ kg.

Step2: Use momentum formula

The formula for momentum is $p = mv$, where $v = 6$ m/s and $m = 26.7$ kg. So $p=26.7\times6 = 160.2$ kg·m/s.

Answer:

160.2 kg·m/s
