ANSWER:
2025 joules
STEP-BY-STEP EXPLANATION:
Given:
Mass (m) = 2 kg
Velocity (v) = 45 m/s
The kinetic energy is given by the following equation:
[tex]K_E=\frac{1}{2}mv^2[/tex]We replacing:
[tex]\begin{gathered} K_E=\frac{1}{2}\cdot2\cdot45^2 \\ K_E=2025\text{ J} \end{gathered}[/tex]The kinetic energy is equal to 2025 joules.
