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.

Special relativity can be used to study an object in which frame of reference?
Tresset [83]
Special relativity led the path for general relativity; special relativity is in a sense a special application of the rules of general relativity. While general relativity is in position to tackle all of these problems, special relativity can tackle only problems in inertial frames. Inertial frame means that the frame of reference is inot accelerating. So, we disqualify answers A and D. However, remember that moving in a circle means that there is an acceleration, the centrifugal one, even if the speed does not change. Hence C is also incorrect.
The correct answer is B, since if there is no change in velocity, the frame does not accelerate and it is inertial.

100 newtons 5 seconds how do you find the momentum
UNO [17]
 F = ma = m dv/dt

F dt = m dv

integrate both sides ( assuming constant force , mass) , zero inital conditions

Ft = mv

mv = P

P = Ft = 5 * 100 = 500 N.s

One car drives north at 60 mph. Another car leaces 30 minutes later and drives south at 50 mph. How long will it take for the tw
Softa [21]

After the second car starts out,

D = 30 + 110 H

360 = 30 + 110 H

330 = 110 H

H = 330/110

H = 3 hours after the second car leaves.

That's 3.5 hours after the first car leaves.

A projectile of mass 6.8 kg kg is shot horizontally with an initial speed of 14.5 m/s from a height of 26.7 m above a flat deser
sleet_krkn [62]

Answer:

Explanation:

Given

mass of projectile m=6.8\ kg

initial horizontal speed u_x=14.5\ m/s

height h=26.7\ m

Considering vertical motion

velocity gained by projectile during 26.7 m motion

v^2-u^2=2 as

v=final velocity

u=initial velocity

a=acceleration

s=displacement

v^2-(0)^2=2\times (9.8)\times (26.7)

v=\sqrt{523.32}

v=22.87\ m/s

Horizontal velocity will remain same as there is no acceleration

final velocity v_{net}=\sqrt{(v)^2+(u_x)^2}

v_{net}=\sqrt{733.57}=27.08\ m/s

Initial kinetic Energy K_i=\frac{1}{2}mu_x^2

K_i=\frac{1}{2}\times 6.8\times (14.5)^2=714.85\ J

Final Kinetic Energy K_f=\frac{1}{2}mv_{net}^2

K_f=\frac{1}{2}\times 6.8\times (27.08)^2

K_f=2493.30\ J

Work done by all the force is equal to change in kinetic Energy of object

Work done by gravity is W_g

W_g=\Delta K

W_g=2493.30-714.85=1778.45\ J
