Vng Power Rating Power is the rate of doing work. Power depends on the amount of work done in a specific time. It is measure in joules/second or watts which is the SI unit. Horsepower often used in measuring power of machines but is not an SI unit. One horsepower is equivalent to 750 watts. Read, analyze, and solve the following problems using the GUFSA template. Show your complete solution. Round off your final answer to the nearest hundredths. 1. A piano mover pushes a piano with a force of 200 N, moving it 12 m in 15 s. With how much power does the piano mover need to push?
