How much power in watts is needed to cut a lawn in 50 mins if the work involved is 100000J?

To find the power in watts needed to cut the lawn, you can use the formula ( \text{Power} = \frac{\text{Work}}{\text{Time}} ). Here, the work done is 100,000 J and the time taken is 50 minutes, which is 3,000 seconds. Thus, power required is ( \frac{100,000 , \text{J}}{3,000 , \text{s}} \approx 33.33 , \text{W} ). Therefore, approximately 33.33 watts of power is needed.
