<h2>Q: Derive the Third Equation of Motion</h2> <p><strong>To Derive:</strong> <br> v² = u² + 2as</p> <h3>Given:</h3> <ul> <li>Initial velocity = u</li> <li>Final velocity = v</li> <li>Acceleration = a</li> <li>Displacement = s</li> </ul> <h3>Step 1: From First Equation of Motion:</h3> <p>v = u + at</p> <p>⇒ t = (v - u)/a</p> <h3>Step 2: Use Second Equation:</h3> <p>s = ut + ½at²</p> <h3>Step 3: Substitute t in s = ut + ½at²</h3> <p>s = u × (v - u)/a + ½a × [(v - u)/a]²</p> <p>Simplifying the expression gives:</p> <p><strong>v² = u² + 2as</strong></p> <h3>Conclusion:</h3> <p>This is the third equation of motion.</p> <p><strong>Need PDF Notes?</strong> Join Telegram: <a href="http...
