Answer:

The answer is 3600 J

Explanation:

The kinetic energy (KE) of an object given it's mass and velocity can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass of the object

v is the velocity

From the question

m = 0.5 kg

v = 120 m/s

So we have

[tex]KE = \frac{1}{2} \times 0.5 \times {120}^{2} \\ = \frac{1}{4} \times 14400[/tex]

We have the final answer as

3600 J

Hope this helps you
