Question

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

Answer 1

A.
The marlin has more momentum.




B.
The salmon has more momentum.




C.
Both have the same momentum.




D.
Both have no momentum.

Answer 2

The momentum is calculated by multiplying the mass times the velocity.
\[p = m \times v\]
Where p is the momentum in kg m/s, m is the mass in kg, and v is the velocity.
Since the velocity for each is the same, you should be able to solve this with the information here.

Answer 3

and F=dp/dt=delta p / delta t =m delta v / delta t = m a
so Ft=I=delta p
