# BulletCart Energy Loss#

A $${{params.mbg}} g$$ bullet travels at $${{params.vb}} m/s$$ and strikes a stationary $${{params.m}} kg$$ block, embedding in it.

## Part 1#

Calculate the energy lost in the impact as an absolute value.

Please enter in a numeric value in $$J$$.

## Part 2#

Calculate the energy lost in the impact as a percentage of the original system energy.

Please enter in a numeric value in $$%$$.
