If a car with a mass of 1200 kg is moving at a speed of 15 m/s, what is its kinetic energy? (2021)

If a car with a mass of 1200 kg is moving at a speed of 15 m/s, what is its kinetic energy? (2021)

Step 1: Identify the formula for kinetic energy, which is Kinetic Energy = 0.5 × mass × velocity².
Step 2: Write down the mass of the car, which is 1200 kg.
Step 3: Write down the speed of the car, which is 15 m/s.
Step 4: Substitute the mass and speed into the formula: Kinetic Energy = 0.5 × 1200 kg × (15 m/s)².
Step 5: Calculate (15 m/s)², which is 225 m²/s².
Step 6: Multiply 1200 kg by 225 m²/s² to get 270000 kg·m²/s².
Step 7: Multiply 270000 kg·m²/s² by 0.5 to get 135000 J.
Step 8: Conclude that the kinetic energy of the car is 13500 J.

Kinetic Energy – Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 0.5 × mass × velocity².
