One horsepower (1 hp) is the unit of power based on the work that a horse can do it in one second. This is defined, in English units, as a force of 550lb that can move an object 1 foot in 1 s. In SI, 1 hp equals 745.7 W or 745.7 J of work delivered in 1 s. Suppose you have a horse that delivers 745.7 W of power, but that it does the work in only 0.55 s. How much work has this horse done?
