SUMMARY
The discussion centers on calculating the change in water speed when the kinetic energy increases by a factor of 2.25. The key equation used is the kinetic energy formula, Ek = 0.5mv². By setting Ek(new) to 2.25 times Ek(old), the relationship between the new and old speeds is derived. The final calculation shows that the new speed is the square root of 4.5, indicating a speed change factor of approximately 2.12.
