A dog has a momentum of 60 kilogram meters per second west The dog has a velocity of 3 meters per second west What is the mass of the dog?

To find the mass of the dog, we can use the formula for momentum, which is momentum = mass × velocity. Given the momentum of 60 kg·m/s and a velocity of 3 m/s, we can rearrange the formula to find mass: mass = momentum / velocity. Thus, the mass of the dog is 60 kg·m/s ÷ 3 m/s = 20 kg.
