Suppose a 125 N force is applied to a lawnmower handle at an angle of 35° with the ground and the lawnmower moves along the surface of the ground. If the lawnmower moves 56 m, how much work was done? (hint: use cos to find the x of force vector)

Workdone is 5734.06Nm.

Explanation:

Given the following data;

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;

mg = weight = 125N

Substituting into the equation, we have;

Fx = 102.39N

Workdone is given by the formula;

Workdone = 5734.06Nm

Therefore, the work done by the lawnmower is 5734.06Nm.
