Un cuerpo se mueve en línea recta segun la ecuación x=10+20t-4.9t2 (x está expresado en metros y t en segundos). ¿cuál es la longitud del camino recorrido al cabo de 3.0 segundos? porfa es para mañana

La longitud del camino recorrido es de 25.9 [m]

Explanation:

Se reemplaza el valor de tiempo en segundos en la ecuación dada de desplazamiento

x=10+20*(3) - 4.9*(3)^2

x= 25.9 [metros]

The equation that we have is:

X = 10m + 20m/s*t -4.9m/s^2*t^2

where x is the position of an object in meters and t is in seconds.

Now, we want to know the distance that the object moves in 3 seconds.

This can be calculated as:

X(3) - X(0) = 10m + 20m/s*3 -4.9m/s^2*3^2 - 10m = 15.9m

So the object moves 15.9 metes in the first 3 seconds.

now in Spanish.

La ecuación que tenemos es:

X = 10m + 20m / s * t -4.9m / s ^ 2 * t ^ 2

donde x es la posición de un objeto en metros yt está en segundos.

Ahora, queremos saber la distancia que se mueve el objeto en 3 segundos.

Esto se puede calcular como:

X (3) - X (0) = 10m + 20m / s * 3 -4.9m / s ^ 2 * 3 ^ 2 - 10m = 15.9m

Entonces el objeto se mueve 15.9 metes en los primeros 3 segundos.

i don't know, you need to give me some answers.

explanation:

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
