A kid is on a stationary sled, on

gregori [183]

The mass of the kid and the sled is 50.0 kg

Explanation:

The sled starts to move when the force applied becomes larger than the maximum force of static friction, which is given by

$F_{max} = \mu_s mg$

where

$\mu_s$ is the coefficient of static friction

m is the mass of the kid + the sled

$g=9.8 m/s^2$ is the acceleration of gravity

Here the sled starts moving when the force applied is 61.2 N, so

$F_{max}=61.2 N$

And we also know

$\mu_s = 0.125$

Therefore, we can find the mass of the kid and the sled by re-arranging the equation:

$m=\frac{F_{max}}{\mu_s g}=\frac{61.2}{(0.125)(9.8)}=50.0 kg$

What is the term used to describe a force that equals the sum of two or more forces

kirill115 [55]

<h3>NET FORCE </h3>

The net force is equal to the sum of two forces acting in the same direction on an object. The net force is always bigger than the individual forces in this scenario.

Pun zapato de golf tiene 10 tacos cada uno con un área de 0.01 pulgadas en contacto con el piso suponga que caminar hay un insta

Mars2501 [29]

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.
