Answer:
The answer is 8,100 J
Explanation:
The kinetic energy of a body when 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
mass of object = 50 kg
velocity = 18 m/s
It's kinetic energy is
[tex]KE = \frac{1}{2} \times 50 \times {18}^{2} \\ = 25 \times 324[/tex]
We have the final answer as
8100 J
Hope this helps you
