A standard hammer has a head made of steel which bounces off the nails it hits. A special “dead blow” hammer has a hollow head which is loosely filled with tiny spheres of lead or sand that can rattle around inside the head. If you have a standard and a “dead blow” hammer whose heads have the same mass and you swing them at the same velocity, which one will deliver higher impulse to the nail it strikes? A. The normal hammer B. The dead blow hammer
