What pressure does the boy produce on the floor with a mass of 48 kg and the area of the soles of his shoes is 320 cm2.
August 28, 2021
m = 48 kg.
S = 320 cm ^ 2 = 0.032 m ^ 2.
g = 9.8 m / s ^ 2.
Pressure P is the ratio of the force F to the area on which this force acts S.
P = F / S.
The boy is affected by the force of gravity F = m * g.
P = m * g / S.
P = 48 kg * 9.8 m / s ^ 2 / 0.032 m ^ 2 = 14700 Pa.
Answer: the boy produces pressure on the floor, presses P = 14700 Pa.
