Answer:
[tex] K. E. = 6 \times {10}^{6} \: Joule [/tex]
Step-by-step explanation:
Since the automobile is in motion, therefore it has kinetic energy (K. E.)
Here, m = 1200 kg, v = 100 m/s
[tex] \because \: K. E. = \frac{1}{2} m {v}^{2} \\ \\ \therefore \: K. E. = \frac{1}{2} \times 1200 \times {(100)}^{2} \\ \\ \therefore \: K. E. = 600 \times 10000\\ \\ \therefore \: K. E. = 6000000 \: Joule \\ \\\therefore \: K. E. = 6 \times {10}^{6} \: Joule[/tex]
