Question

The momentum of an ostrich is calculated to be 5,400 kg*km / hr Its mass is known to be 120 kg. Was the ostrich moving or standing still?

Answer 1

As
momentum=5,400kg*km/hr
mass=120kg
momentum=mass*velocity
velocity=45km/hr or 12.5ms^-1
so ostrich is moving with 12.5ms^-1

Answer 2

The correct answer to the question is : The ostrich is motion.

Step-by-step explanation:

As per the question, the momentum of ostrich P = 5400 Kg. Km/hr.

The mass of the ostrich m = 120 Kg.

The momentum of a body is defined as the product of mass with velocity.

Mathematically P = mv.

The velocity of the ostrich v is calculated as -

v =
`(P)/(m)`

=
`(5400)/(120)\ Km/hr`

= 45 Km/hr

Hence, the ostrich is in motion as it is moving with a velocity of 45 Km/hr.
