Calculate the power of a horse that produces 180,000 joules of work while running a race in 6 seconds.

Power is calculated as work done divided by time taken. In this case, the work done is 180,000 joules and the time taken is 6 seconds.

Power = 180,000 joules / 6 seconds = 30,000 watts

Therefore, the power of the horse is 30,000 watts.
