Determine the pressure on the table of a pile of books with a total mass of 1.5 kg, the area of contact of which with it is 300 cm2.
m = 1.5 kg.
g = 10 m / s2.
S = 300 cm2 = 0.3 m2.
P -?
Pressure P is the ratio of the force F to the surface area S on which this force acts: P = F / S.
Books press down on the table with the force of their weight. The weight of the books is determined by the formula: F = m * g, where m is the mass of the books, g is the acceleration of gravity.
The formula for determining the pressure of books will take the form: P = m * g / S.
P = 1.5 kg * 10 m / s2 / 0.3 m2 = 50 Pa.
Answer: the pressure of the books on the table is P = 1.5 kg * 10 m / s2 / 0.3 m2 = 50 Pa.
