## Homework Statement

a 600 kg canon, initially at rest, exploded upon firing and broke into three fragments. One fragment of mass of 200 kg traveled east at 40m/s and a second fragment of mass 300 kg traveled due south at 20 m/s. What was the velocity of the third fragment?

## Homework Equations

sum of P = sum of P'

0= P1 + P2 + P3

## The Attempt at a Solution

I'm not sure whether I'm supposed to use trig or something to find the missing velocity.

Any help would be GREATLY appreciated.
