1) Final proton energy

2) Final alpha energy (or velocity)

3) Final alpha angle

But you also have 3 conserved quantities. Can you name them?

kinetic, momentum , cant think of the last one.

1) Final proton energy

2) Final alpha energy (or velocity)

3) Final alpha angle

you only need conservation of momentum

I don't know initial and finial speed.you only need conservation of momentum

You know kinetic energy, you should know the proton mass, so you can compute initial velocity.I don't know initial and finial speed.

You have 3 unknowns:

1) Final proton energy

2) Final alpha energy (or velocity)

3) Final alpha angle

But you also have 3 conserved quantities. Can you name them?

Momentum is a vector quantity. Does this help?kinetic, momentum , cant think of the last one.
