Massa mobil 100kg, energi kinetiknya 100 joule. Berapa kecepatan mobil?

Ek. = 1/2 m. v"
100 = 1/2 100.v"
100 = 50.v"
100/50 = v"
2 = v"
√2 = v




Maafkan jika kurang tepat

Ek = 1/2 × m × v²
100 J = 1/2 × 100 kg × v²
100 kg.m²/s² = 1/2 × 100 kg × v²
100 kg.m²/s² = 50 kg × v²
100 kg.m²/s² ÷ 50 kg = v²
2 m²/s² = v²
v = √(2 m²/s²)
v = √2 m/s
v = 1,41 m/s
