Question

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?

Answer 1

`K. E. = 6 * {10}^(6) \: Joule`

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. = (1)/(2) m {v}^(2) \\ \\ \therefore \: K. E. = (1)/(2) * 1200 * {(100)}^(2) \\ \\ \therefore \: K. E. = 600 * 10000\\ \\ \therefore \: K. E. = 6000000 \: Joule \\ \\\therefore \: K. E. = 6 * {10}^(6) \: Joule`
