Answer:
The answer is
720 Joules
Explanation:
The kinetic energy of a body can be found by using the formula
[tex]K.E = \frac{1}{2} {mv}^{2} [/tex]
where
m is the mass
v is the velocity / speed
From the question
mass = 10 kg
velocity = 12 m/s
Substitute the values into the above formula and solve
That's
[tex]KE = \frac{1}{2} \times 10 \times {12}^{2} \\ = 5 \times 144 \: \: [/tex]
We have the final answer as
720 Joules
Hope this helps you
