Question

How much power, in watts, is needed to cut a lawn in 50 min if the work involved is 100,000 J?

Answer 1

33.33 Watt

Step-by-step explanation:

we know that P= W/t

W= work

t= time (in seconds)

so here

W= 100,000J

and t= 50 min= 50×60 sec= 3000 s

so P= 100,000/ 3000

=100/3 = 33.33Watt
