Question

the power rating of an electric lawn mower is 2200 watts. if the lawn mower was used for 30 mins, and 650 Newtons of force was used, how much distance was covered?

Answer 1

To calculate the distance covered by the lawn mower, we can use the concept of work done. Work done is equal to the force applied multiplied by the distance traveled.

Step-by-step explanation:

To calculate the distance covered by the lawn mower, we can use the concept of work done. Work done is equal to the force applied multiplied by the distance traveled.

In this case, the force applied is 650 Newtons and the power rating of the electric lawn mower is given as 2200 watts. Power is defined as the work done per unit of time. So, we can calculate the time taken to cover the distance using the power rating.

Once we have the time and the force, we can calculate the distance covered using the formula:

Distance (d) = Force (F) × Time (t)

So, plugging in the values, we get:

d = 650 N × (30 mins × 60 s/min)

Converting the time to seconds, we have:

d = 650 N × 1800 s

Now, we can calculate the distance:

d = 1,170,000 Ns
