Answer:
The answer is 243 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 = 54 kg
v = 3 m/s
The kinetic energy is
[tex]KE = \frac{1}{2} \times 54 \times {3}^{2} \\ = 27 \times 9 \\ = 243 \: \: \: \: \: [/tex]
We have the final answer as
243 J
Hope this helps you
