Answer:

Las presión ejercida por los tacos sobre el suelo es 900 libras por pulgada cuadrada.

Explanation:

Según la Física, comprendemos que la presión es igual a la fuerza dividida por área. En este caso, el peso de la persona dividida por área total de los tacos de los zapatos de golf suponiendo una distribución uniforme de la fuerza. Es decir:

\sigma = \frac{W}{n\cdot A_{T}} (Eq. 1)

Donde:

\sigma - Presión, medida en libras por pulgada cuadrada.

W - Peso de la persona, medida en libras.

n - Cantidad de tacos en los zapatos, adimensional.

A_{T} - Área del taco, medida en pulgadas cuadradas.

Si conocemos que W = 180\,lb, n = 20 y A_{T} = 0.01\,in^{2}, la presión es:

\sigma = \frac{180\,lb}{(20)\cdot (0.01\,in^{2})}

\sigma = 900\,psi

Las presión ejercida por los tacos sobre el suelo es 900 libras por pulgada cuadrada.

Why would an egg break immediately when it hits the ground?
Elza [17]

As an egg falls towards the floor, it begins to travel faster and faster. When it slams into the floor, the egg is stopped almost immediately. This force of the floor against the eggshell is too large, so it breaks.
