1. Convert mass to kilograms:

* 30 grams = 0.03 kilograms (since 1 kg = 1000 g)

2. Use the kinetic energy formula:

* Kinetic Energy (KE) = 1/2 * mass * velocity²

* KE = 1/2 * 0.03 kg * (200 m/s)²

* KE = 0.015 kg * 40000 m²/s²

* KE = 600 Joules (J)

Therefore, the kinetic energy of the 30 gram bullet traveling at 200 m/s is 600 Joules.
