Problem

A gardener pushes a lawn mower of weight

50\,\text{N}

by applying a force along the handle that makes an angle of

20^{\circ}

below the horizontal. If the coefficient of static friction between the wheels and the ground is

0.25

, determine the least magnitude of the applied force required to set the mower in motion. \,(Take

g = 9.8\,\text{m}\,\text{s}^{-2}
