Answer:
Ekin = 250000 [J]
Explanation:
The kinetic energy of a body or object can be calculated based on the mass and the speed with which it moves. This energy can be easily calculated by means of the following equation.
[tex]E_{kin}=\frac{1}{2} *m*v^{2}[/tex]
where:
m = mass = 200 [kg]
v = velocity = 50 [m/s]
Now replacing:
[tex]E_{kin}=\frac{1}{2} *200*(50)^{2}\\E_{kin}=250000[J][/tex]
