The amount of energy dedicated to kinetic energy will be 400 J.Option C is correct.
The energy possessed by the body by the virtue of motion is known as kinetic energy. It is found as the product of mass and the square of the velocity.
Part of the energy in each machine that exists dissipates to the medium in the form of heat, friction with the surface, and other forms of energy dissipation.
If the entire kinetic energy loses 200 J in the form of heat and 200 J in the form of friction this quantity of energy has been wasted and cannot be utilized as kinetic energy.
The energy goes toward kinetic energy will be ;
Kinetic energy = Electric energy -Heat-friction
Kinetic energy = 800-200-200
Kinetic energy =400 J
Hence, the amount of energy dedicated to kinetic energy will be 400 J.Option C is correct.
