Question

If riding a lawnmower engine exerts 19 hp in one minute to move the lawnmower how much work is done

Answer 1

the work done by the lawnmower is 236.14 J.

Step-by-step explanation:

Given;

power exerted by the lawnmower engine, P = 19 hp

time in which the power was exerted, t = 1 minute = 60 s.

1 hp = 745.7 watts

The work done by the lawnmower is calculated as follows;

`Work = Energy = (Power)/(time) \\\\Work = ((19 * 745.7))/(60) = 236.14 \ J`

Therefore, the work done by the lawnmower is 236.14 J.
