| **The worker presses on a shovel weighing 8 kg. What is the pressure the shovel exerts on the ground if its tip measures 0.6m 0.002m.**

To calculate the pressure of the used shovel on the ground, we use the formula: P = F / S = m * g / (L * B).

Variables and constants: m – mass (m = 8 kg); g – acceleration due to gravity (g ≈ 10 m / s2); L is the length of the tip (L = 0.6 m); B is the width of the tip (B = 0.002 m).

Let’s perform the calculation: P = m * g / (L * B) = 8 * 10 / (0.6 * 0.002) ≈ 66.7 * 10 ^ 3 Pa (66.7 kPa).

Answer: The pressure of the used shovel on the ground is 66.7 kPa.
