Answer:

Kinetic energy, E = 321.44 Joules

Explanation:

It is given that,

Mass of the man, m = 82 kg

Speed of the man, v = 2.8 m/s

Let E is the kinetic energy of the man. The energy possessed by an object due to its motion is called kinetic energy. The mathematical formula is given by :

[tex]E=\dfrac{1}{2}mv^2[/tex]

[tex]E=\dfrac{1}{2}\times 82\times (2.8)^2[/tex]        

E = 321.44 Joules

So, the kinetic energy of the man is 321.44 Joules. Hence, this is the required solution.
