Answer:
The answer is 2736 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 = 0.38 kg
v = 120 m/s
We have
[tex]KE = \frac{1}{2} \times 0.38 \times {120}^{2} \\ = \frac{1}{2} \times 0.38 \times 14400 \\ = 0.38 \times 7200[/tex]
We have the final answer as
2736 J
Hope this helps you
