Answer:
Workdone is 5734.06Nm.
Explanation:
<u>Given the following data;</u>
Force applied = 125N
Angle = 35°
Distance = 56m
To find the workdone by the lawnmower, we would first of all find the horizontal component of the force applied.
Where;
- Fx represents the horizontal force.
- m is the mass of an object.
- g is the acceleration due to gravity.
- d is the angle of inclination (theta).
mg = weight = 125N
Substituting into the equation, we have;
Fx = 102.39N
Workdone is given by the formula;
Workdone = 5734.06Nm
<em>Therefore, the work done by the lawnmower is 5734.06Nm</em>.
