Determine the pressure that a young man bravely withstands at a disco when his girlfriend

Determine the pressure that a young man bravely withstands at a disco when his girlfriend weighing 450N accidentally steps on his foot with her heel. The area on which the girl is leaning at the same time is 5 cm square. How and why will the pressure exerted on the boy’s leg change if the girl appears at the disco in comfortable sneakers?

F = 450 N.
S = 5 cm ^ 2 = 0.0005 m ^ 2.
P -?
Pressure P is the ratio of the force F to the area S on which it acts.
P = F / S.
P = 450 N / 0.0005 m ^ 2 = 900000 N.
The pressure on the boy’s leg will be less if the girl is wearing sneakers, because the area on which the force will act will increase.
Answer: the pressure on the boy’s leg will be P = 900,000 N.
