Question

Compute the kinetic energy in Joules of a 12.0g rifle bullet
travelling at 250m/s.

Answer 1

Explanation:

How much work will be done by a 30-gram bullet that is traveling at 200 m/s? From energy conservation, the amount of work the bullet can do is at most equal to its kinetic energy. So the most work the bullet can do is 600 Joules.
