Sagot :
Answer:
[tex]\displaystyle KE = 169254 \ J[/tex]
General Formulas and Concepts:
Energy
Kinetic Energy Formula: [tex]\displaystyle KE = \frac{1}{2}mv^2[/tex]
- KE is kinetic energy (in J)
- m is mass (in kg)
- v is velocity (in m/s)
Explanation:
Step 1: Define
[Given] m = 790 kg
[Given] v = 20.7 m/s
Step 2: Solve
- Substitute in variables [Kinetic Energy Formula]: [tex]\displaystyle KE = \frac{1}{2}(790 \ kg)(20.7 \ m/s)^2[/tex]
- [KE] Evaluate exponents: [tex]\displaystyle KE = \frac{1}{2}(790 \ kg)(428.49 \ m^2/s^2)[/tex]
- [KE] Multiply: [tex]\displaystyle KE = (395 \ kg)(428.49 \ m^2/s^2)[/tex]
- [KE] Multiply: [tex]\displaystyle KE = 169254 \ J[/tex]
