KE - 1/2 * m * v ^ 2
Using the formula for calculating kinetic energy:
KE = 1/2 * m * v^2
Where KE is the kinetic energy, m is the combined mass of the horse and its jockey, and v is the velocity of the horse in meters per second.
Substituting the given values:
KE = 1/2 * 512 kg * (180 m/s)^2
KE = 504206 J
Therefore, the kinetic energy of the horse and jockey is 504206 J. Answer: 504206 J.
