Answer:
45,000 J
General Formulas and Concepts:
Energy
Kinetic Energy Formula: [tex]\displaystyle KE = \frac{1}{2}mv^2[/tex]
- m is mass (in kg)
- v is velocity (in m/s)
Explanation:
Step 1: Define
Identify variables
[Given] m = 900 kg
[Given] v = 10 m/s
Step 2: Solve for KE
- Substitute in variables [Kinetic Energy Formula]: [tex]\displaystyle KE = \frac{1}{2}(900 \ kg)(10 \ m/s)^2[/tex]
- Evaluate exponents: [tex]\displaystyle KE = \frac{1}{2}(900 \ kg)(100 \ m^2/s^2)[/tex]
- Multiply: [tex]\displaystyle KE = (450 \ kg)(100 \ m^2/s^2)[/tex]
- Multiply: [tex]\displaystyle KE = 45000 \ J[/tex]
