Question 3 NECO • 2024 • AGRICULTURAL_SCIENCE • practical

A farmer is using a hand hoe to break up a shallow layer of soil. The hoe has a blade that is 15 cm wide and the farmer inserts the blade to a depth of 10 cm. The soil shear strength is 30 kN·m⁻². The farmer pushes the hoe so that the handle makes an angle of 30° with the horizontal and moves the blade forward a distance of 2.0 m.

( a )

Calculate the area of the blade that is in contact with the soil (in m²).

( b )

Determine the shear force that must be overcome by the farmer (in N).

( c )

Find the component of this force acting in the direction of movement (horizontal component) (in N, to the nearest N).

( d )

Calculate the total work done by the farmer in moving the hoe through the 2.0 m distance (in joules, to the nearest joule).
