# Split Blocks#

A 10 $$kg$$ block is initially at rest on a sheet of ice. An internal explosion occurs, splitting the object into two pieces of masses $$m_A$$ = 5 $$kg$$ and $$m_B$$ = 5 $$kg$$. After the explosion, block A is measured to have a velocity of $$\vec{v_A}$$ = 4.9 $$m/s$$.

## Part 1#

What is the velocity of block $$B$$?

Please enter in a numeric value in $$m/s$$.

## Part 2#

Assuming that there’s no friction, how much energy did the explosion release?

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