In order to find the speed of a horse we must understand the formula for speed. The formula is
v = Δs/Δt
where Δs is the change in distanceand Δt is the change in time. Thisis the only formula that is needed in order to find the speedor velocity of a horse.
In order to calculate this formula, the two starting valuesthat are needed are the change in distance and the elapsed timethroughout the distance the horse ran, Once these values are obtainedyou simply plug them in to the formula and get the average velocityof the horse.
For my calculations I obtained many statistics of race resultsof certain horses. One of these horses was Secretariat(the winner of the Triple Crown in 1973). I found the race resultswith the race distance and the winning time. From these numbersI found out the velocity of Secretariat when he won theTriple Crown. The velocity seemed to be constant with the othervelocities that I had previously found.
All of the results that I Have found in this project have beennumbers based on the horse breed known as the thoroughbred. Thethoroughbred breed is the common breed used in horse racing andis known to be one of the fastest breeds on the planet.
After all my calculations have been completed, I have cometo the conclusion that the average velocity for the fastest breedof horse (the thoroughbred) is about 17 m/s. This is a remarkablefact considering that 17 m/s is roughly 38 miles per hour.This is just as fast as a car yet it is an animal that is runningthis fast.
Overall, we can see that horses are very fast animals and arefascinating to watch. Especially when the Triple Crown is on theline.
