Question

A man pushes a lawn mower on a level lawn with a force of 201 N. If 44% of this force is directed forward, and 65 W of power is expended in pushing the mower 5.6 m, how much time is spent in pushing the mower this distance?

Expert Solution

Step 1

Given Data:

The force with which the man pushes the lawn mover is given as f = 201N.

The percentage of force f in forward direction is given as $% F_{h}$ = 44%.

The power required in pushing the lawn mover 5.6m is given as p=65W.

The distance moved by the lawn mover is given as d = 5.6m.
