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:  

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”.

Resolviendo para “ X “ : X=Vx (t)

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

X = 20 m

Problem #2: An apple is thrown upward with an initial velocity of +24.0 m/s. a. Sketch the apple's trip and label what you know.
bogdanovich [222]

Answer:

The answer is below

Explanation:

a) The initial velocity (u) = 24 m/s

We can solve this problem using the formula:

v² = u² - 2gh

where v = final velocity, g= acceleration due to gravity = 9.8 m/s², h = height.

At maximum height, the final velocity = 0 m/s

v² = u² - 2gh

0² = 24² - 2(9.8)h

2(9.8)h = 24²

2(9.8)h = 576

19.6h = 576

h = 29.4 m

b) The time taken to reach the maximum height is given as:

v = u - gt

0 = 24 - 9.8t

9.8t = 24

t = 2.45 s

The total time needed for the apple to return to its original position = 2t = 2 * 2.45 = 4.9 s

a projectile is shot horizontally from the edge of a cliff, 230m above the ground. the projectile lands 300m from base of the cl
bekas [8.4K]

Answer:

The time taken by the projectile to hit the ground is 6.85 sec.

Explanation:

Given that,

Vertical height of cliff = 230 m

Distance = 300 m

Suppose, determine the time taken by the projectile to hit the ground.

We need to calculate the time

Using second equation of motion

s=ut+\dfrac{1}{2}gt^2

Where, s = vertical height of cliff

u = initial vertical velocity

g = acceleration due to gravity

Put the value in the equation

230=0+\dfrac{1}{2}\times9.8\times t^2

t=\sqrt{\dfrac{230\times2}{9.8}}

t=6.85 sec

Hence, The time taken by the projectile to hit the ground is 6.85 sec.
