f) Power is the rate of doing work

Power (In Watts) = work done (in Joules) / time (in seconds)

g) 1 watt is the rate of working at one Joule per second

13. P = Wd/t = 1000/5 = 200W

14. P = Wd/t

Work done = force x distance = 300 x 2

P = 600/6 = 100W

15. P = Wd/t

Work done = f x d = 3000 x 10

P = 30000/4 = a) 7500W => b) 7.5kW
