Which statement best compares the momentum of a 5-kilogram fish swimming at a speed of 10 meters/second and a 2-kilogram fish swimming at a speed of 10 meter/second?

Respuesta :

p = m.v
p1 = 5x10 = 50 kg. m/s
p2 = 2x10 = 20 kg. m/s
so the momentum of the first fish is higher than the second one.

Answer:

Momentum

Explanation:

Momentum can be defined as the product of velocity of a moving body and its mass.

In this case we have two fishes with same velocity but different masses hence their momentum will also be different.

So as per the definition,  p = m * v

where p is the momentum

m is the mass of the object and v is the velocity of object.

for comparison let us consider p1 is the momentum of first fish and p2 is the momentum of second fish.

p1 = 5 * 10

   = 50 kg m/s

and p2 = 2 * 10

            = 20 kg m/s

hence momentum of p1 is greater than momentum of p2
