Answer:
2482 Kg.m/s
Explanation:
Momentum is a product of mass of an object and its velocity with consideration to the direction of velocity and expressed as, p=mv where m represent mass of the ostrich and v is the velocity in m/s, p is momentum.
Substituting the mass of ostrich with 146 kg and the velocity as 17 m/s then the momentum of the ostrich is equal to
P=146*17=2482 kg.m/s
Therefore, the momentum of ostrich is equal to 2482 kg.m/s
