Split Blocks#

A 11 \(kg\) block is initially at rest on a sheet of ice. An internal explosion occurs, splitting the object into two pieces of masses \(m_A\) = 7 \(kg\) and \(m_B\) = 4 \(kg\). After the explosion, block A is measured to have a velocity of \(\vec{v_A}\) = 5.8 \(m/s\).

Part 1#

What is the velocity of block \(B\)?

Answer Section#

Please enter in a numeric value in \(m/s\).

Part 2#

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

Answer Section#

Please enter in a numeric value in \(J\).
