The component of the momentum of piece b, pbx, f, is measured to be +500 kg⋅m/s after the explosion. find the component of the momentum pax, f of piece a after the explosion.

To solve this problem we will use the concepts related to the conservation of the Momentum. From finding the changes at the initial and final moment we will have the value of the components of the pieces after the explosion. Let's start:

Where,

Momentum of the object before explosion

= Final momentum of piece A

= Final momentum of piece B

The object is at rest before the explosion, then

The piece B is moving along positive x direction, then we have that

Replacing,

The component of momentum in the part A is of in the negative direction of X.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
