In a controlled experiment, engineers test a firecracker. The firecracker has mass $ m $ and is placed at rest on a horizontal surface. When the firecracker is lit, it explodes and breaks apart into two pieces. In the first trial, one piece with mass $ \dfrac{m}{2} $ moves to the left with speed $ v_L $ and the other piece moves to the right with speed $ v_R $. A second trial is performed with an identical firecracker, and one piece with mass $ \dfrac{3m}{4} $ moves to the left, again with speed $ v_L $. What will the speed of the other piece be in this second trial?
