The book is on the table. The weight of the book is 0.8 kg. The area of its contact with the table is 0.08 m2. Determine the pressure of the book on the table.

m = 0.8 kg.
S = 0.08 m ^ 2.
g = 10 m / s ^ 2.
P -?
The pressure P is the force F applied to the unit area S.
To find the pressure P, you need to divide the force by the area to which it is applied.
P = F / S.
The body is affected by gravity F = m * g.
P = m * g / S.
P = 0.8kg * 10m / s ^ 2 / 0.08m ^ 2 = 100 Pa.
Answer: the pressure of the book on the table is P = 100 Pa.
