A dog running with a speed of 1.9 m/s has a momentum of 17kg•m/s what is the mass of the dog

Mass of the dog = 9kg (approximate)

Explanation:

Velocity (speed) = 1.9m/s

Momentum (P) = 17kgm/s

Mass=?

P=M x V

17kgm/s = M x 1.9m/s

Making mass (M) the subject of the formula:

M = (17kgm/s) / (1.9m/s) = 8.974kg

Approximately, the mass of the dog is equal to 9kg.
