Question

What is the momentum of a dog of mass 20 kg that is running east with a speed of 3 m/s?

Answer 1

60 kg * m/s east.

Step-by-step explanation:

Momentum is a vector quantity, so you must include direction in the answer. Work by the guy above me ^_^

Answer 2

60 kg.m/s

Step-by-step explanation:

Momentum is the product of mass and velocity

p=m*v where m is mass in kg and v is velocity in m/s

Given that;

m=20kg and v=3m/s then;

p= 20×3= 60kgm/s
