Answer:
The answer is 40 Joules
Explanation:
The kinetic energy of a body can be found by using the formula
[tex]KE = \frac{1}{2} {mv}^{2} [/tex]
where
m is the mass
v is the velocity
From the question
mass = 5 kg
velocity = 4 m/s
Substitute the values into the above formula and solve
We have
[tex]KE = \frac{1}{2} \times 5 \times {4}^{2} \\ = \frac{1}{2} \times 5 \times 16 \\ = 5 \times 8[/tex]
We have the final answer as
40 Joules
Hope this helps you
