A football player kicks a football off a tee with a speed of 21 m/s at an angle of 51°. what is the horizontal component of the velocity?

Answers

Answer:

The horizontal component of the velocity is approximately 13.22 m/s

Explanation:

The velocity of the kick which the football player gives the ball = 21 m/s

The angle of the path taken by the ball = 51°

The velocity can be represented vectorially, showing the vertical and horizontal components as follows;

v = 21 × cos(51°)·[tex]\hat i[/tex] + 21 × sin(51°)·[tex]\hat j[/tex]

Where we have;

The horizontal component of the velocity = 21 × cos(51°)

The vertical component of the velocity = 21 × sin(51°)

Therefore;

The horizontal component of the velocity = 21 × cos(51°) ≈ 13.22 m/s

The horizontal component of the velocity ≈ 13.22 m/s.

– Un automóvil A viaja hacia el este a 80 Km/h, mientras que un segundo automóvil B viaja en la misma carretera a 70 Km/h. Determine la velocidad del automóvil B medida desde el automóvil A si: a) Viajan en sentido contrario acercándose uno al otro. B) Viajan en el mismo sentido.

Answers

Answer:

la respuesta esta abajo

Explanation:

La velocidad de un objeto A relativa a otro objeto B es la velocidad que el objeto A parecería tener para un observador que se mueve con B.

a) La velocidad relativa de dos cuerpos que se mueven en la dirección opuesta es la suma de su velocidad. Por lo tanto:

Velocidad relativa = 80 + 70 = 150 km / h

b) La velocidad relativa de dos cuerpos que se mueven en la misma dirección es la diferencia entre su velocidad. Por lo tanto:

Velocidad relativa = 80 - 70 = 10 km / h

14. Trying to be on time for class, a girl moves at 1.4 m/s down a 52 m-long 7 points
hallway, 1.8 m/s down a much more crowded hallway that is 79 m long, and
the last 25 m to her class at 2.4 m/s. How long does it take her to reach her
class?



88S

Answers

Answer:

Option (2)

Explanation:

To find the time taken by the girl we will use the formula,

Time = [tex]\frac{\text{Distance traveled}}{\text{Speed}}[/tex]

Time taken by a girl who moves down 52 m long and 1.4 m per second,

[tex]t_1=\frac{52}{1.4}[/tex]

[tex]t_1[/tex] = 37.14 sec.

Time taken to move through crowded hallway,

[tex]t_2[/tex] = [tex]\frac{79}{1.8}[/tex]

[tex]t_2=43.89[/tex] sec

Time taken to cover 25 m with speed 2.4 meter per sec,

[tex]t_3=\frac{25}{2.4}[/tex]

[tex]t_3=10.42[/tex] sec

Total time taken by the girl = [tex]t_1+t_2+t_3[/tex]

                                             = 37.14 + 43.89 + 10.42

                                             = 91.45

                                             ≈ 91 seconds

Answers

Answer:

c) more energy is trapped, which leads to an increase in Earth's global temperature

Explanation:

Greenhouse effect is caused by the trapping of the reflected energy from the surface of the earth into the atmosphere by some gases. Thus with time causes more energy to be trapped in the atmosphere, which cause an increase in the average ambient temperature of the earth. Because the energy could not escape out into space beyond the earth's atmosphere. Therefore, an increase in Earth's global temperature.

So that the correct option in the given question is C.

Dos pilotos suicidas, que están inicialmente a una distancia de 500 m entre sí, deciden chocar directamente de frente arrancando ambos desde el reposo. Ambos autos pueden desarrollar una aceleración máxima constante de 15 m/s2 . Si el piloto A arranca un segundo antes que el piloto B, encuentra: a) la posición donde los autos chocan, medida a partir de la posición donde arranca el piloto A, y b) la rapidez relativa de la colisión (la rapidez de B con respecto a A justo antes de la colisión, ó viceversa).

Answers

Answer:

a) El punto de colisión de los dos automóviles desde donde parte el conductor del automóvil A es de aproximadamente 293,14 metros.

b) La velocidad del automóvil A, en relación con la velocidad del automóvil B, es de 15 m / s

Explanation:

Los parámetros del movimiento son;

La distancia entre ambos coches = 500 m

La aceleración de ambos coches = 15 m / s²

La dirección de movimiento de ambos coches = uno hacia el otro

La hora de inicio del conductor A = Un segundo antes de la hora de inicio del conductor B

Por lo tanto, de la ecuación de movimiento, tenemos;

s = u · t + 1/2 · a · t²

v² = u² + 2 · a · s

Dónde;

u = La velocidad inicial de los autos = 0 (los autos parten del reposo)

t = El tiempo de movimiento de una aceleración dada

a = La aceleración = 15 m / s²

s = La distancia recorrida en el tiempo t

Por lo tanto, para el controlador A, tenemos;

s₁ = 0 × (t + 1) + 1/2 × 15 × (t + 1) ² = 7.5 × (t + 1) ²

s₁ = 7.5 × (t + 1) ²

Para el conductor B, tenemos;

s₂ = 0 × t + 1/2 × 15 × t² = 7.5 × t²

s₂ = 7,5 × t²

Dado que ambos chocan a lo largo del camino de 500 m, tenemos;

s₁ + s₂ = 500 metros

∴ 7.5 × (t + 1) ² + 7.5 × t² = 500

∵ s₁ + s₂ = 7.5 × (t + 1) ² + 7.5 × t²

Lo que da;

15 · t² + 15 · t + 7.5 = 500

15 · t² + 15 · t - 492,5 = 0

Resolver usando la aplicación en línea da; t = -6,25181 o t = 5,25181

Dado que t es un número natural, tenemos el valor correcto para t = 5.25181 segundos

a) Por tanto, el punto de colisión de los dos coches desde donde parte el conductor del coche A es;

s₁ = 7.5 × (t + 1) ² = 7.5 × (5.25181 + 1) ² ≈ 293.14 metros

El punto de colisión de los dos automóviles desde donde parte el conductor del automóvil A ≈ 293,14 metros

b) La semilla de A en el punto de colisión se da de la siguiente manera

Velocidad, v₁ = u + a × (t + 1) = 0 + 15 × (5.25181 + 1) ≈ 93.78

v₁ ≈ 93,78 m / s

La semilla de B en el punto de colisión también se da de la siguiente manera

Velocidad, v = u + a × (t) = 0 + 15 × 5.25181 ≈ 78.78

v₁ ≈ 78,78 m / s

Por lo tanto, la velocidad del automóvil A, en relación con la velocidad del automóvil B, [tex]v_{relative}[/tex] se da como sigue;

 = v₁ - v₂ = 93,78 m / s - 78,78 m / s = 15 m / s

la velocidad del automóvil A, relativa a la velocidad del automóvil B = 15 m/s.

What is a cell wall?A cell wall is a structural layer that surrounds certain types of cells. It can be hard, flexible, or rigid at times. It functions as a filtration system as well as structural support and cell protection. Many eukaryotes, including animals, lack cell walls, though fungi, algae, and plants, as well as the vast majority of prokaryotes, do (except mollicute bacteria). One of their primary functions is to act as pressure channels, preventing the cell from over-expanding when water enters.The polysaccharides cellulose, hemicelluloses, and pectin make up the primary cell wall of land plants. Other polymers, such as lignin, suberin, and cutin, are frequently anchored to or embedded in plant cell walls.

6. The race car in the previous problem slows from
36 m/s to 15 m/s over 3.0 s. What is its average
acceleration?

Answers

Answer:

a_AV - 15 m/s – 36 m/s =-70 m/s2. At. 3.0 s.

Explanation:

The average acceleration of the car as it slows down is  -5 m/s².

Given is a race car that slows down from 36 m/s to 15 m/s in 3 seconds.

initial velocity [u] = 36 m/s

final velocity [v] = 15 m/s

time taken [Δt] = 3 s

We can calculate the acceleration as follows -

a = Δv/Δt

a = (v - u) / Δt

a = (15 - 30)/3

a = -15/3

a = -5 m/s²

Therefore, the average acceleration of the car as it slows down is

-5 m/s².

Answer: The average angular velocity  for a rotating pulley is 3 rev/s, 180 rpm, 6π rad/s.

The pulley turns rotating when the rope tugged and completes 12 rev in 4 seconds.

How to determine the average angular velocity?

 If we consider a pulley rotating in a same axis, every point in the pulley has the same angular velocity.

Formula for angular velocity:

                    ω = Δθ / Δt

The average angular velocity can be defined as the ratio of the angular displacement to the time.

                                θ = 12 rev, t = 4s

             1 revolution = 2π rad

It can be solved as:

      Revolutions / second: 

      rev / s = 12 / 4      

                  =  3

      Revolutions per minute:

        rpm   =  ( 12/4) × 60
