The kinetic energy of a 25-gram bullet traveling at 500 m/s is?

Answer 1

To calculate the kinetic energy of an object, you can use the formula:

Kinetic Energy = (1/2) * mass * velocity^2

Given:
Mass = 25 grams = 0.025 kg (since 1 kg = 1000 grams)
Velocity = 500 m/s

Now substituting the values in the formula,

Kinetic Energy = (1/2) * 0.025 * (500)^2

Kinetic Energy = 0.5 * 0.025 * 250000

Kinetic Energy = 3125 Joules

Therefore, the kinetic energy of a 25-gram bullet traveling at 500 m/s is 3125 Joules.
