Answer:

The answer is

7,840,000 J

Step-by-step explanation:

The kinetic energy KE of an object given it's mass and velocity 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 = 20000kg

v = 28 m/s

It's kinetic energy is

$KE = (1)/(2) * 20000 * {28}^(2) \\ = 10000 * 784$

We have the final answer as

Hope this helps you
