1. When a baseball player hits a home run, the baseball receives agreater impulse from the bat than the bat does from theball.truefalse2. In a collision between a light hydrogen molecule and a heavywater molecule, the momentum lost by one molecule is exactly the same as the momentum gained by the other molecule.truefalse3. As a tile falls from the roof of a building to the ground itsmomentum is conserved.truefalse4. A rubber ball moving horizontally at 8.50 m/s hits a brick walland bounces back with exactly the same speed but in the oppositedirection. During this collision, its change in momentum iszero.truefalse5. In a collision between a small car and a large truck, the carand the truck undergo the same change in their velocities.truefalse
