3. Which hammer delivers more energy?Explain your reasoning.

More information is needed to answer this question. "Which hammer" implies a comparison between two or more hammers. To determine which delivers more energy, we need details about the hammers. Specifically, we need to know either:<br /><br />* **The mass and velocity of each hammer:** A hammer's kinetic energy is calculated using the formula KE = 1/2 * m * v², where 'm' is mass and 'v' is velocity. The hammer with the greater kinetic energy delivers more energy upon impact.<br /><br />* **The work done by each hammer:** If we know the force applied by each hammer and the distance over which that force is applied, we can calculate the work done (Work = Force x Distance). The hammer that does more work delivers more energy.<br /><br />Provide more information about the hammers being compared, and I can help you determine which delivers more energy.<br />
