Question

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

Answer 1

Mass of the dog = 9kg(approximate)

Step-by-step 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.
