Gunakan Gravitasi = 10 m/s²
Energi Mekanik (dititik tertinggi) = Energi Potensial = m × g × h = 2 × 10 × 5 = 100 Joule
Energi Potensial di titik 2 m = m × g × h = 2 × 10 × 2 = 40 Joule
Energi Kinetik = Energi Mekanik - Energi Potensial = 100 - 40 = 60 Joule
Energi Kinetik = ½ × m × v² = ½ × 2 × v² = v² = 60
v = √60 m/s
Semoga Membantu ^_^
