Kinetic Energy of a Bullet

Asked by Nandini Kapoor · 1 year ago

What is the kinetic energy of a 10g bullet traveling at 300 m/s?

1 Answer

To find the kinetic energy of the 10g bullet:
  1. Convert mass to kg: 10g = 0.01 kg
  2. Use the formula: Kinetic Energy (KE) = ½ × mass (m) × velocity² (v²)
  3. KE = ½ × 0.01 kg × (300 m/s)²
  4. KE = 0.005 × 90,000 = 450 J
The kinetic energy of the bullet is 450 Joules. This demonstrates the high energy of even small, fast-moving objects.
