Understanding Kinetic Energy

Kinetic energy is the energy an object possesses due to its motion. It's calculated using the following formula:

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

Applying the Formula

* Mass (m) = 10 kg

* Velocity (v) = 5 m/s

Calculation

KE = (1/2) * 10 kg * (5 m/s)²

KE = 5 kg * 25 m²/s²

KE = 125 Joules (J)

Answer

The kinetic energy of the 10-kg dog chasing the car at 5 m/s is 125 Joules.
