please help me with this hw problem

[ineedhelp]

find the mass of a projectile when fired at 275m/s if it is to have the same momentum as a 145g projectile fired at 325m/s

[Integral]

What is the definition of momentum?

[ineedhelp]

i dont know it doesnt say any where

You must not have looked very many places.

Momentum is defined as

p = mv

where p is momentum, m is mass, and v is velocity.

if any one can help ive been working on this for an hour

How can we find the momentum of the 145g object? How could we find the momentum of the 275 m/s object? These two momentums are equal, so what do we do with things that are equal?
