Respuesta :

Given

a) m = 6000 kg, v = 11 m/s

b) m = 0.200 kg, v = 300 m/s

c) m = 18000 kg, v = 0 m/s

Procedure

Momentum is a physics term; it refers to the quantity of motion that an object has.

[tex]p=mv[/tex]

where m is mass and v is velocity

a) p = mv

p = 6000 kg * 11 m/s

p = 66000 kg*m/s

b) p = mv

p = 0.2 kg * 300 m/s

p = 60 kg*m/s

c) p = mv

p = 18000 kg * 0 m/s

p = 0 kg*m/s

The biggest momentum is with the elephant. And the car has the greatest inertia (mass).
