I have a physics question for all physics students out there,
2 blocks of wood of equal mass are set up an equal distance away from 2 guns. Each gun contains a bullet of equal mass, one is rubber one is aluminum. When fired the rubber bullet bounces off the block of wood while the aluminum bullet imbeds itself in the wood. The bullets both travel at equal velocities and the surface on which the blocks sit is ice so friction is minimal. Which block of wood would travel further?
