If a 1000 kg car is moving at a speed of 15 m/s, what is its kinetic energy?

If 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 is given as 1000 kg.
Step 2: Identify the speed of the car. The speed is given as 15 m/s.
Step 3: Write down the formula for kinetic energy: Kinetic Energy = 0.5 × mass × velocity².
Step 4: Substitute the mass into the formula: Kinetic Energy = 0.5 × 1000 kg × velocity².
Step 5: Substitute the velocity into the formula: Kinetic Energy = 0.5 × 1000 kg × (15 m/s)².
Step 6: Calculate (15 m/s)², which is 225 m²/s².
Step 7: Now substitute this value back into the formula: Kinetic Energy = 0.5 × 1000 kg × 225 m²/s².
Step 8: Multiply 0.5 × 1000 kg = 500 kg.
Step 9: Now multiply 500 kg by 225 m²/s²: Kinetic Energy = 500 kg × 225 m²/s² = 112500 J.
Step 10: The final answer for the kinetic energy is 112,500 Joules.

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