Answer:
Explanation:
Given:
Weight = 400N
Area = 100cm^2
If 1cm^2 = 1×10^-4m^2
Hence 100 cm^2 = 0.01m^2
Pressure = force/area .........1
Force = ma = mg which is also the weight of the girl. Hence substitute the values into 1
P = 400/0.01
P = 40000 N/m^2
The pressure she puts on the ground is 40000 N/m^2
