Explanation:
The question says that "Does a 60 kg person running at 4 m/s have more kinetic energy than a 10 gram projectile at 300 m/s ? "
Speed of a person is 4 m/s
Mass of a person is 60 kg
Kinetic energy of a person is :
So,
Mass of a projectile is 10 grams or 0.01 kg
Speed of a projectile is 300 m/s
Kinetic energy of a projectile is :
So, it is clear that the kinetic energy of a person is more than that of the kinetic energy of a projectile.
