# Momentum Explosion Question

### cvc121

1. The problem statement, all variables and given/known data
A 50kg object explodes into three pieces. Piece 1 flies off at 12m/s [N 30o E], piece 2 has velocity 10m/s [ S ]. If the mass of piece 1 is 25kg and piece 2 is 12kg, find the mass and velocity of piece 3.

2. Relevant equations

3. The attempt at a solution
My attempt is shown below. Can anyone confirm my work? Not sure if my vector diagram is drawn correctly. Thanks! All help is very much appreciated!

I dont think that is correct.
you should divide momentum into components (x and y)

furthermore, what is V3= xxx Kg*m/s ... are kg*m/s a velocity dimension?

The working looks good, solving from the vector diagram. The correct vector was identified that makes the net momentum zero, and its components determined.
