rgies, use the formulas KE = 1/2 mv² and PE = mgh, and apply the conservation of mechanical energy principle: initial potential energy plus initial kinetic energy equals final kinetic energy plus final potential energy. What units are used for kinetic and potential energy in word prob
tential energy (PE) = m g h Initial kinetic energy (KE) = 0 Use conservation of energy: PE_initial + KE_initial = PE_final + KE_final At ground level, PE_final = 0, KE_final = ? Calculate initial potential energy: PE_initial = m g h = 10 × 9.8 × 20 = 1960 J Set energy equa
