guys tolongin JANGAN PAKE AI, pake cara yang bener kalo bisa ditulis di buku

Kinetic Energy = (1/2) (mass) (speed squared)
Mass = 100 kg Speed = 10 km/s = 10,000 m/s Speed squared = 100,000,000 m²/s²
1/2 (M)(V²) = 1/2 (100) (100,000,000) = 5,000,000,000 joules (5 x 10⁹ J)
That's 5 billion joules.
That's the amount of energy a 100-watt light bulb uses in 579 days.

KE=1/2 x mass x speed^2 Substitute:
KE=1/2 x 100 x 10000^2 5000000000J of KE So either 5 gigajoules Or 5x10^9J

The kinetic energy of a 100.0-kg meteor approaching Earth at a speed of 10.0 km/s is calculated to be 5 billion joules (5 x 10⁹ J). This value is derived using the formula for kinetic energy, incorporating the mass and the speed of the meteor converted into meters per second. Such energy is vast, showing the immense impact potential of meteors.
