A 1,200-kg automobile is traveling at a velocity of 100 m/s. Is its energy potential or kinetic? How much energy does it possess

Rama09 [41]

Answer:

$K. E. = 6 \times {10}^{6} \: Joule$

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

$\because \: K. E. = \frac{1}{2} m {v}^{2} \\ \\ \therefore \: K. E. = \frac{1}{2} \times 1200 \times {(100)}^{2} \\ \\ \therefore \: K. E. = 600 \times 10000\\ \\ \therefore \: K. E. = 6000000 \: Joule \\ \\\therefore \: K. E. = 6 \times {10}^{6} \: Joule$
