When digging a hole for planting trees, the boy put on a shovel with a force of 100N

When digging a hole for planting trees, the boy put on a shovel with a force of 100N. What is the area of the shovel’s edge if the pressure on the ground is 800 kPa?

Given:

F = 100 Newton – the force with which the boy pressed the shovel;

P = 800 kPa = 800000 Pascal – shovel pressure on the ground.

It is required to determine S (square meter) – the area of the edge of the shovel.

To determine the area of the shovel edge, you must use the following formula:

P = F / S, hence:

S = F / P = 100/800000 = 1/8000 = 0.000125 square meters = 1.25 square centimeters.

Answer: The area of the shovel edge is 1.25 square centimeters.
