The kinetic energy of the car is 50,000 Joules. Steps: 1. Identify the given values: Mass (m) = 1000 kg; Velocity (v) = 10 m/s 2. Recall the formula for kinetic energy (KE): KE = 0.5 × m × v² 3. Substitute the given values into the formula: KE = 0.5 × (1000 kg) × (10 m/s)² 4. Calculate the square of the velocity: (10 m/s)² = 100 m²/s² 5. Perform the multiplication: KE = 0.5 × 1000 kg * 100 m²/s²; KE = 500 × 100 kg·m²/s²; KE = 50,000 J (since 1 Joule = 1 kg·m²/s²)

Answer

The kinetic energy of the car is 50,000 Joules.

Step-by-step solution

5 steps

Steps:

Identify the given values
- Mass (m) = 1000 kg
- Velocity (v) = 10 m/s
Recall the formula for kinetic energy (KE)
- KE = 0.5 * m * v^2
Substitute the given values into the formula
- KE = 0.5 * (1000 kg) * (10 m/s)^2
Calculate the square of the velocity
- (10 m/s)^2 = 100 m^2/s^2
Perform the multiplication
- KE = 0.5 * 1000 kg * 100 m^2/s^2
- KE = 500 * 100 kg·m^2/s^2
- KE = 50,000 J (since 1 Joule = 1 kg·m^2/s^2)
