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?
As
momentum=5,400kgkm/hr
mass=120kg
momentum=massvelocity
velocity=45km/hr or 12.5ms^-1
so ostrich is moving with 12.5ms^-1
The correct answer to the question is : The ostrich is motion.
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 = \(\frac{P}{m}\)
= \(\frac{5400}{120}\ Km/hr\)
= 45 Km/hr
Hence, the ostrich is in motion as it is moving with a velocity of 45 Km/hr.
