Answer:

The answer is 450 J

Step-by-step explanation:

The kinetic energy of a body can be found by using the formula


KE = (1)/(2) m {v}^(2) \\

where

m is the mass

v is the velocity

From the question

m = 100 kg

v = 3 m/s

We have


KE = (1)/(2) * 100 * {3}^(2) \\ = 50 * 9

We have the final answer as

450 J

Hope this helps you
