Answer:
The answer is
2560 J
Explanation:
The kinetic energy 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
v is the velocity
From the question
m = 80 kg
v = 8 m/s
The kinetic energy is
[tex] KE = \frac{1}{2} \times 80 \times {8}^{2} \\ = 40 \times 64[/tex]
We have the final answer as
2560 J
Hope this helps you
