Como anticipan la caída del proyectil, con movimiento parabólico para que el misil no haga daño

Physics
1 answer:
Elena L [17]3 years ago
8 0

Answer:

Conociendo la velocidad inicial del proyectil y el angulo de lanzamiento con respecto ala horizontal.

Explanation:

Para poder anticipar la caída del proyectil es importante conocer la velocidad inicial del proyectil y el angulo de disparo del proyectil con respecto a la horizontal.

A continuación se presenta un diagrama o esquema donde se pueden ver estas variables y se explicaran a la brevedad:

Para poder encontrar el rango que es la máxima distancia horizontal recorrida por el proyectil debemos utilizar la siguiente ecuación:

x=(v_{o})_{x} *t\\where:\\(v_{o})_{x} = velocidad inicial  x-component [m/s]\\t= time [s]

Para poder encontrar el tiempo debemos utilizar la siguiente ecuación:

y=(v_{y} )_{o}*t-0.5*g*t^{2}  \\donde:\\(v_{y} )_{o}= velocidad inicial componente y [m/s]\\g = gravity = 9.81 [m/s^2]\\t = time [s]

En la anterior ecuación, igualamos y = 0, ya que cuando el proyectil cae al suelo la distancia vertical es cero. De esta manera podemos encontrar el tiempo t, ya que conocemos la velocidad inicial del proyectil en la componente y.

Seguidamente reemplazamos t en la primera ecuacion y encontramos la distancia x o el rango.

or Ethernet, if an adapter determines that a frame it has just received is addressed to a different adapter it discards the fram
Artist 52 [7]

For Ethernet, if an adapter determines that a frame it has just received is addressed to a different adapter

a. it discards the frame without sending an error message to the network layer

b. it sends a NACK (not acknowledged frame) to the sending host

c. it delivers the frame to the network layer, and lets the network layer decide what to do

d. it discards the frame and sends an error message to the network layer

Answer:

Option A

Explanation:

The nodal address has to match the signal message address for it to function well but if the it doesn't match the nodal receiver address, it disregards it.

Radio waves and microwaves are similar because they both have
tekilochka [14]

The correct answer is

b. low frequencies and low energy.

In fact, microwaves and radio waves have frequency up to 10^{10}-10^{11} Hz, which are really low compared, for instance, to the frequency of gamma rays (10^{20} Hz). Moreover, the energy of an electromagnetic wave is directly proportional to its frequency:

E=hf

where h is the Planck constant and f the frequency; therefore, low frequency means also low energy.

z jaka maksymalna predkoscia porusza sie przez krotka chwile rowerzysta jezeli dysponuje moca maksymalna 420w i przy predkosci z
qwelly [4]

Answer:

12 m/s

Explanation:

English Translation

At what maximum speed is the cyclist traveling for a short time if he has a maximum power of 420W and at this speed he must overcome the resistance 35N.

The Power, P, expended by a moving body with velocity, v, moving against a resistive force of F is given as

P = Fv

P = 420 W

F = 35 N

v = ?

420 = 35v

v = (420/35) = 12 m/s

In Polish/Po polsku

Moc P, wydana przez poruszające się ciało z prędkością v, poruszająca się przeciw sile oporu F, jest podana jako

P = Fv

P = 420 W

F = 35 N

v = ?

420 = 35v

v = (420/35) = 12 m/s

Hope this Helps!!!

When analyzing forces, it is allowable to break the motion and forces into horizontal and vertical components.
jonny [76]

The statement above is TRUE.

When analyzing forces it is permitted to break the motion and forces into horizontal and vertical components. This is especially true for two dimensional projectile motion, in order to simplify the calculation, the forces and the motion has to be broken down into horizontal and vertical components. The vertical component is affected by the force of gravity while the horizontal component is not affected by gravity for short displacements. With greater displacement, the force of gravity comes into play.
