SUMMARY
The total energy calculation for a mass of 5 kg at a height of 300 mm with a velocity of 1.5 m/s results in 20.33 Joules. This is derived using the formulas for potential energy (PE = mgh) and kinetic energy (KE = 0.5mv²). The potential energy is calculated as 14.7 J and the kinetic energy as 5.63 J, confirming the total energy as the sum of both components. The calculations are accurate and consistent with physics principles.
