Homework Statement
The diagram shows a proton moving with Ek of (0.178)(10-12)J towards a stationary nucleus X. The proton hits X and is absorbed.
The resulting nucleus splits into two alpha particles, which move off in the directions shown with equal Ek of (1.481)(10-12)J
1. Calculate the mass equivalence of the net energy release during the collision.
2. Calculate the rest mass of the nucleus X. The mass of a proton is (1.673)(10-27) kg and the mass of an alpha particle is (6.645)(10-27)kg
Homework Equations
E=mc2
The Attempt at a Solution
First question I have no idea how to do that.
second question, I simply added the proton mass + alpha particle mass (which is a wrong answer since energy is used for binding energy)
I sort of get the concepts but can't do them mathematically...
Please help me step by step.
