An athlete exerts 3000 W of power when he takes 10.2 seconds to run the race. How much work does the athlete do?

Answer :

Kinetic energy (K.E.) is inversely proportional to the square of an object's velocity and its mass: K.E. = 1/2 m v2. When a mass is measured in kilograms and a speed is measured in meters per second.

The kinetic energy is measured in kilogram-meters squared per second squared.

Where can I find velocity?

By dividing the entire distance traveled by the time it took the object to go a certain distance, you may calculate the object's initial velocity. V, d, and t are the three variables that make up the equation V = d/t.

How is kinetic energy calculated mathematically?

Kinetic energy (KE) is defined as the product of the mass of an item multiplied by the square of its velocity. Consider this: The kinetic energy of an object with a mass of 10 kilograms (m = 10 kg) travelling at a speed of 5 m/s (v = 5 m/s) is equal to 125 joules, or (1/2 * 10 kg) * 5 m/s2.
