Solution:
Mass of the object (m) = 80kg
Velocity of the object (v) = 55m/s
We know that,
[tex] \: \: \: \: \: \: \bigstar\:\: \sf\large\boxed{\tt{{K.E= \frac{1}{2}×mv^2}}} \: \bigstar[/tex]
Putting values in the formula
[tex]\implies\sf{K.E =\dfrac{1}{2}× 80 × (55)^2}[/tex]
[tex]\implies\sf{K.E=\dfrac{1}{2}×80×3025}[/tex]
[tex]\implies\sf{K.E=\dfrac{1}{\cancel2}×{\cancel{242000}}}[/tex]
[tex]\therefore\sf{K.E=121000J}[/tex]
To Find :
The kinetic energy of the body

Solution :
Given, Mass of Body = 80 kg
Velocity of Body = 55 m/s
[tex] \tt{ \implies \: ke = \frac{1}{2 } \times m {v}^{2} }[/tex]
[tex] \implies \tt{ke = \frac{1}{2} \times 80 \times {55}^{2} }[/tex]
[tex] \implies \tt{ke = 40 \times 3025}[/tex]
[tex] \implies \tt{kinetic \: energy = 121000}[/tex]
hence, Kinetic energy = 1,21,000 J
