A 500 kilogram marlin and a 20 kilogram salmon are swimming at the same velocity. How does the momentum of the two fish compare?

Question

stormfire1 · Answer

Since they are moving at the same velocity and momentum is mass * velocty, the 500kg marlin will have 25 times the momentum as the salmon.

so b?

i mean a

oops...yes, the one with larger mass has more momentum in this case since they are both travelling at the same velocity.  So it's the marlin.

anonymous · Answer

well the equation for momentum is p (momentum) = v*m (velocity x mass)

if they are both travelling at the same velocity, but one's mass is higher, then you can see that v*m for the fish with the higher mass will give it a larger momentum. Think of you and your friend running into a wall. If you're both running at 10 meters/second yet you're 100kg and he's 200 kg, he's going to feel the impact of the wall much harder than you will because he had more momentum than you did when you both ran into it.

What is the relationship between the mass, velocity, and momentum of an object?

A. 

The mass of an object is directly proportional to its velocity and momentum.


B. 
The velocity of an object is directly proportional to its mass and momentum.

C. 
The momentum of an object is directly proportional to its mass and velocity.
D. 
Keeping the momentum constant, the velocity of an object is directly proportional to its mass.
