The pressure exerted on the block on the ground in N/m² is 200N/m².
<h3>What is pressure?</h3>
The pressure is the amount of force applied per unit area.
Given is a 5000 Newton block rests on the ground over 25 m² of area.
Pressure p = Force/Area
Put the values, we get
p = 5000 /25
p = 200 N/m²
Hence, pressure exerted on the block on the ground is 200 N/m².
