A 1000 kg car is moving at a speed of 15 m/s. What is its kinetic energy?

A 1000 kg car is moving at a speed of 15 m/s. What is its kinetic energy?

Step 1: Identify the mass of the car. The mass (m) is 1000 kg.
Step 2: Identify the speed of the car. The speed (v) is 15 m/s.
Step 3: Write down the formula for kinetic energy: Kinetic Energy = 0.5 * m * v².
Step 4: Calculate v² (the speed squared). v² = (15 m/s) * (15 m/s) = 225 m²/s².
Step 5: Multiply the mass by v². 1000 kg * 225 m²/s² = 225,000 kg*m²/s².
Step 6: Multiply the result by 0.5. 0.5 * 225,000 kg*m²/s² = 112,500 J.
Step 7: The kinetic energy of the car is 112,500 Joules (J).

Kinetic Energy – Kinetic energy is the energy that an object possesses due to its motion, calculated using the formula KE = 0.5 * m * v², where m is mass and v is velocity.
