Question

Как помогите пж Рассчитать давление, производимое на пол девочкой массой 60 кг, если площадь подошв ее ботинок, соприкасающихся с полом, 0,04 м2.

Answer 1

Дано: m=60кг, S=0,04 м2, g=9,81м/с^2
Найти: P-?
Решение:
P=F/S=mg/S=60кг*9,81м/с^2:0,04м^2=14715Па
Ответ:14715 Па

Answer 2

p1 = F÷S

F = p2

p2 = m×g

g = 9,8 Н

Решение:

F = 60×9,8 = 588

p1(которое девочка оказывает на пол) = 588÷0,04 = 14700

Объяснение:

Ответ: 14700 давление оказываемое девочкой на по

Answer 3

Calculating Pressure Exerted by a Girl

To calculate the pressure exerted by a girl with a mass of 60 kg and a shoe sole area of 0.04 m^2, we can use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

Where: - Force (F) is the weight of the girl, which can be calculated using the formula: F = mass × acceleration due to gravity - Area (A) is the area of the shoe sole in contact with the floor

Let's calculate the pressure step by step.

Calculating the Force Exerted by the Girl

The force exerted by the girl can be calculated using the formula F = mass × acceleration due to gravity. The acceleration due to gravity is approximately 9.81 m/s^2.

F = 60 kg × 9.81 m/s^2

The force exerted by the girl is approximately 588.6 N.

Calculating the Pressure

Now, we can use the formula for pressure to calculate the pressure exerted by the girl on the floor.

Pressure (P) = Force (F) / Area (A)

P = 588.6 N / 0.04 m^2

After performing the calculation, the pressure exerted by the girl on the floor is approximately 14715 Pa.

So, the pressure exerted by the girl with a mass of 60 kg and a shoe sole area of 0.04 m^2 is approximately 14715 Pa.
