Which has more momentum, an object with a mass of #3kg# moving at #14m/s# or an object with a mass of #12kg# moving at #6m/s#?

1 Answer

Answer:

The object with the mass of 12kg has more momentum.

Explanation:

Know that #p=mv#, where p is momentum, v is velocity, and m is mass. Since all the values are in SI units already, there is no need for conversion, and this becomes just a simple problem of multiplication.
1.#p=(3)(14)=42 kg*m/s#

2.#p=(12)(6)=72kg*m/s#

Therefore, the object of m= 12kg has more momentum.
