This is for my physical science homework it would mean alot if anyone helped me out or just wrote out how to do this equation
Power is the rate at which energy is expended. Power = energy / time 72,000 J / 48 s = 1,500 J/s By definition, a Watt is one Joule per second 1,500 J/s = 1,500 W = 1.5 kW --- There used to be a power unit called the Horsepower (HP); however, there were different definitions of Horsepower (depending if one was talking of mechanical power, electrical power, or whatever else). In Watts, the different Horsepower go from roughly 735 W to 750 W. If we take 1 HP = 750 W, then 2 HP = 1,500 W
