Pressure p is given by the equation:
p=F/A, where F is the force and A is the area that the force acts upon.
F=500 N
cm² need to be converted to m². We know that there is 10000 cm² in 1 m² so 200 cm² / 10000 cm²=0.02 m².
A=200 cm² = 0.02 m²
Now we need to insert the values into the equation to get the pressure p:
p=500/200=5/2=2.5 N/m²
Also, 1 N/m²=10000 Pa so:
p=2.5 N/m² * 10000 = 25000 Pa
The pressure between the boy and the ground is p=2.5 N/m² or p=25000 Pa.
