You have also the total power generated is 200W
To figure out the kind of exercises, you need to master the definition of each unit. for example
power: watt (W) is joule/sec
Work: is Newton. meter = Joule
To obtain the work done by the adult, we have to convert the power (watt) into a work by multiplying by the time (
* seconds = Joule)
10 minutes is 60 * 10 = 600 seconds
200Watt * 600 second = 120000 joules = 120 Kj
So the work is 120Kj
