Homework Statement
A 30g bullet is moving at a horizontal velocity of 500m/s come to a stop 12 cm within a solid wall. What is the change in mechanical energy of the bullet?
Homework Equations
Mechanical energy = 1/2mv^2+mgh
The Attempt at a Solution
The question is for 6 marks, If I had to answer it, I would say the change in mechanical energy would equal the initial kinetic and potential energy of the bullet since unless I am missing something then the bullet has no energy left inside the wall, but I am not sure, so can anyone help me or make suggestions?
