That's not a terribly useful equation. Try using different symbols for different variables, e.g. the two masses and the two speeds. If you find subscripting a pain, combine upper and lower case, like Ma, Mb.Willy_Kingston said:

Work is defined as the force applied to an object multiplied by the distance it moves in the direction of that force. Kinetic energy is the energy an object possesses due to its motion.
Work is directly related to kinetic energy. When work is done on an object, its kinetic energy increases. On the other hand, when work is done by an object, its kinetic energy decreases.
Mass does not directly affect the work and kinetic energy in a race. However, a runner with a larger mass will require more work to be done on them in order to achieve the same amount of kinetic energy as a runner with a smaller mass.
Speed has a direct impact on both work and kinetic energy in a race. The faster a runner moves, the more work is done on them and the higher their kinetic energy. This is because kinetic energy is directly proportional to the square of an object's velocity.
Work can be calculated by multiplying the force applied to an object by the distance it moves in the direction of that force. Kinetic energy can be calculated using the formula 1/2 * mass * velocity^2. In a race, the work done by a runner can be calculated by multiplying their weight by the distance they ran, and their kinetic energy can be calculated using their mass and average speed throughout the race.
