x = 20 m

Calcular las componentes rectangulares de la velocidad inicial

En el lanzamiento horizontal la velocidad inicial vertical (Voy) es igual a cero, por lo que:

Vx = 20 m/s

Voy = 0

Paso No. 2: Anotar los datos para X y para Y. Recuerde que las velocidades y los desplazamientos

Para “X”Para “Y”Vx = 20 m/st =X =Voy = 0g= -9.81 m/s2Y = -5 m

Paso No. 3: Selección de las ecuaciones a utilizar

Recuerde que “X” que es la distancia horizontal que recorre un proyectil y para calcularla es necesario saber el valor de t (tiempo). Observe que en “Y ” tiene datos suficientes para calcular “t”. Paso 4: Resolver la ecuación considerando que Voy = 0, por lo que el primer término se anula.

Y= gt^2 / 2

Resolviendo para “ t “ :

t = 1.009637 s

Calculo de “ t “

Paso5: Calcular “ X “ utilizando la ecuación:

Resolviendo para “ X “ : X=Vx (t)

X = (20 m/s)(1.09637s)

X = 20 m

Which characteristic does an object with a constant acceleration always have?

Alexus [3.1K]

By definition, speed is the integral of acceleration with respect to time.

We have then:

$v = \int\limits^t_0 {a} \, dt$

As the acceleration is constant, then integrating we have:

$v = a*t + vo$

Where,

vo: constant of integration that corresponds to the initial velocity

We observe then that the speed varies linearly when the acceleration is constant .

Therefore, for constant acceleration, the velocity is changing.

Answer:

an object with a constant acceleration always have:

A. changing velocity

A falling object accelerates from -10.0 m/s to -30.0 m/s. how much time does it take?

Zepler [3.9K]

Answer:

2.04 s

Explanation:

v = at + v₀

(-30.0 m/s) = (-9.8 m/s²) t + (-10.0 m/s)

t = 2.04 s

A ball is suspended by a lightweight string, as shown in the figure above.

Irina18 [472]

<u>Answer </u>

A. 1 and 2

<u>Explanation </u>

At point 1 we have the highest potential energy and the kinetic energy is zero.

At 2 the potential energy is minimum and the kinetic energy is maximum.

The law of conservation of energy says that energy cannot be created nor destroyed. So, the change in P.E = Change in K.E.

P.E = height × gravity × mass. The height referred here is the perpendicular height. Gravity and mass are constant in this case.

From the diagram it can be seen clearly that the vertical height from 2 to 1 is much greater than from 4 to 3.

This shows that the change in P.E is greater between 1 and 2 and so is kinetic energy.

An electron passes through a point 2.83 cm 2.83 cm from a long straight wire as it moves at 35.5 % 35.5% of the speed of light p

igor_vitrenko [27]

Answer:

The magnitude of electron acceleration is $2.34 \times 10^{15}$ $\frac{m}{s^{2} }$

Explanation:

Given:

Distance from the wire to the field point $r = 2.83 \times 10^{-2}$ m

Speed of electron $v = 35.5 \%c$

Current $I = 17.7$ A

For finding the acceleration,

First find the magnetic field due to wire,

$B = \frac{\mu _{o}I }{2\pi r }$

Where $\mu_{o} = 4\pi \times 10^{-7}$

$B = \frac{4\pi \times 10^{-7} \times 17.7 }{2\pi (2.83 \times 10^{-2} ) }$

$B = 12.50 \times 10^{-5}$ T

The magnetic force exerted on the electron passing through straight wire,

$F = qvB$

$F = 1.6 \times 10^{-19} \times 0.355 \times 3 \times 10^{8} \times 12.50 \times 10^{-5}$

$F = 21.3 \times 10^{-16}$ N

From the newton's second law

$F = ma$

Where $m =$ mass of electron $= 9.1 \times 10^{-31}$ kg

So acceleration is given by,

$a = \frac{F}{m}$

$a = \frac{21.3 \times 10^{-16} }{9.1 \times 10^{-31} }$

$a = 2.34 \times 10^{15}$ $\frac{m}{s^{2} }$

Therefore, the magnitude of electron acceleration is $2.34 \times 10^{15}$ $\frac{m}{s^{2} }$
