Final answer:
To calculate speed from binding energy and mass, use the mass-energy equivalence equation (E = mc²) to find the nuclear binding energy from the mass defect, then relate the binding energy to kinetic energy to solve for speed.
Step-by-step explanation:
To find the speed using binding energy and mass, you should use the mass-energy equivalence equation, E = mc², where E is the binding energy, m is the mass, and c is the speed of light in a vacuum (approximately 3.00 × 10⁸ m/s). First calculate the mass defect by comparing the mass of the individual nucleons and the mass of the nucleus, then use the mass defect in the equation to find the binding energy. Once you have the binding energy, you can determine the speed of the particles being affected by this energy by relating the energy to kinetic energy (KE = ½mv²) if that's the context in which speed needs to be found.
