Three friends each do work to push an object across the room. Katie does 400 J of work while pushing her object across the room in 6 seconds. Alice does 300 J of work while pushing her object across the room in 7 seconds. Alyssa does 350 J of work while pushing her object across the room in 5 seconds. Which friend has the largest power output?

The friend that has the largest power output among the three friends is Alyssa with 70 J/s of output power.What is power output?The output power of an object or a device is the rate at which energy is used over a given period of time.Mathematically, output power is given as;P = E/twhere;P is the output powerE is the output energy of the objectt is the time periodThe output power of Katie is calculated as follows;P = 400 J / 6 s = 66.67 J/sThe output power of Alice is calculated as follows;P = 300 J / 7 s = 42.86 J/sThe output power of Alyssa is calculated as follows;P = 350 J / 5 s = 70 J/sThus, the output power of each of the friend depends on the amount of energy applied over a given time period.Learn more about output power here: https://brainly.com/question/20038729#SPJ1
