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
 
Physics news on Phys.org
What is the definition of momentum?
 
i don't know it doesn't 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 anyone can help I've 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?
