My commute to school is a constant distance, but the time it takes to get there fluctuates owing to traffic.

If an object moves with respect to a reference frame, such as when a passenger travels to the back of an airliner or a professor moves to the right with respect to a whiteboard, the item's position changes.

This change in location is described as displacement.

My commute to school is a constant distance, but the time it takes to get there fluctuates owing to traffic,

The initial and the final position of the commute is the same, but the displacement varies with the route which affects my car's speed and where it is in line at stop lights.

Actually Welcome to the Concept of the Projectile Motion.

Since, here given that, vertical velocity= 50m/s

we know that u*sin(theta) = vertical velocity

so the time taken to reach the maximum height or the time of Ascent is equal to

T = Usin(theta) ÷ g, here g = 9.8 m/s^2

so we get as,

T = 50/9.8

T = 5.10 seconds

thus the time taken to reach max height is 5.10 seconds.

Answer:

Explanation:

The mass of the object can be found by using the formula

[tex]m = \frac{2KE}{ {v}^{2} } \\ [/tex]

v is the velocity

KE is the kinetic energy

From the question we have

[tex]m = \frac{2 \times 100000}{ {20}^{2} } = \frac{200000 }{400} = \frac{2000}{4} \\ [/tex]

Answer:

a) [tex] y_{max} = 7.7 m [/tex]

b) y = 7.4 m

Explanation:

a) La altura máxima que alcanza la pelota se puede encontrar usando la siguiente ecuación:

[tex] y_{max} = y_{0} + v_{0y}t - \frac{1}{2}gt^{2} [/tex]    (1)

En donde:  

[tex]y_{0}[/tex]: es la altura inicial = 0

[tex]v_{0y}[/tex]: es la velocidad inicial en y

g: es la gravedad = 9.81 m/s²

t: es el tiempo

Primero debemos encontrar la velocidad inicial en y:

[tex] v_{fy} = v_{0y} - gt [/tex]

Sabiendo que la velocidad final en y es igual a cero (en la altura máxima), y con t = 1.25 s (la mitad del tiempo total) tenemos:

[tex] v_{0y} = gt = 9.81 m/s^{2}*1.25 s = 12.3 m/s [/tex]

Ahora, podemos encontrar la altura máxima:

[tex] y_{max} = v_{0y}t - \frac{1}{2}gt^{2} = 12.3 m/s*1.25 s - \frac{1}{2}9.81 m/s^{2}*(1.25 s)^{2} = 7.7 m [/tex]

b) Podemos encontrar la altura cuando t = 1 s con la misma ecuación (1):

[tex]y_{max} = y_{0} + v_{0y}t - \frac{1}{2}gt^{2} = 12.3 m/s*1 s - \frac{1}{2}9.81 m/s^{2}*(1 s)^{2} = 7.4 m[/tex]

Por lo tanto, la pelota se encontraba a 7.4 m luego de 1 segundo despúes del lanzamiento.

Answer:

t = 0.78 s

Explanation:

Given that,

The height of a diving board, h = 3 m

We need to find the time it take for him to reach the water. Let the time is t./

Using second equation of motion as follows :

[tex]h=ut+\dfrac{1}{2}at^2[/tex]

u is initial velocity, u = 0 and a = g

So,

[tex]h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\cdot3}{9.8}}\\\\t=0.78\ s[/tex]

So, it will take 0.78 seconds to reach the water.

Answer:

L = 1.5 [m]

Explanation:

To find the Force Z we must perform a sum of forces on the Y-axis equal to zero, (it is equal to zero since there is no movement, the beam is in equilibrium).

ΣFy = 0

- 30 - 20 - 40 + Z = 0

Z = 90 [N]

Now to find the length of the beam, we must perform a sum of moments equal to zero at the midpoint of the beam, where the load Z is applied.it is important to clarify that the moment generated by the force of 30[N] tends to rotate the beam counterclockwise (is taken as positive), while the load of 20 [N], tends to rotate the beam Clockwise (is taken as negative).

ΣM = 0

+ (30*0.5) - (20*x) = 0

15 = 20*x

x = 15/20

x = 0.75 [m] (this is the half of the distance)

L = 2*x

L = 2*0.75

L = 1.5 [m]

Given :

A jogger runs 5.0 km on a straight trail at an angle of 60° south of west.

To Find :

The southern component of the run rounded to the nearest tenth of a kilometre.

Solution :

We know, southern component is given by :

[tex]d = Dsin \ \theta\\\\d = 5\times sin \ 60^{\circ}\\\\d = -4.33\ km[/tex]

Here, negative sign indicates south direction.

Therefore, the southern component of the run rounded to the nearest tenth of a kilometre is 4.3 km.

Hence, this is the required solution.

The southern component of the run in nearest tenth is 4.3 km.

The given parameters:

The southern component of the run is calculated by finding the equivalent vertical component of the distance covered by the runner as follows;

[tex]d_y = d \times sin(\theta)\\\\d_y = 5 \ km\times 60\\\\d_y = 4.3 \ km[/tex]

Thus, the southern component of the run in nearest tenth is 4.3 km.

Answer:

a) 60kg

Explanation:

mass is not affected by gravity

The mass of Joe on the moon is approximately 60 kg. Hence, option (a) is correct.

Given data:

The weight of Joe is, W = 600 N.

The weight of any object is the product of mass and gravitational acceleration of an object. It is the expressed as,

W = mg

Here,

m is the mass of Joe.

g is the gravitational acceleration.

Solving as,

W = mg

600 = m × 10

m = 60 kg.

Thus, we can conclude that the mass of Joe on the moon is approximately 60 kg. Hence, option (a) is correct.

We observe that in figure D , angle made by refracted ray with normal is greatest . So figure D is the answer.

The  image where the angle of refraction is the greatest is the image D

The angle of refraction is the angle that the refracted ray made with the x-axis.

The higher the angle between the refracted ray and the x-axis, the higher the angle of refraction and vice versa.

Hope this helped!! :)

The initial height of the pumpkin is 23.52m and the final vertical velocity of the pumpkin is 47.04 m/s.

Initial horizontal speed, u = 2.5 m/s

horizontal distance covered , d = 12m

So the time taken is:

t = d/u

t = 12/2.5 s

t = 4.8s

Now, the initial vertical speed, v = 0

So the vertical distance traveled by the pumpkin will be equal to the initial height of the pumpkin:

s = vt + ¹/₂gt²

s = 0.5 × 9.8 × 4.8 m

s = 23.52m

Final vertical velocity:

v' = v + gt

v' = 9.8 × 4.8 m/s

v' = 47.04 m/s

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options. However, one material that is good candidate for conducting electricity without reacting with other materials is metallic vanadium dioxide. This is because of the inability of this electrical conductor to conduct heat (an unusual property for all other electrical conductors) and thus makes it difficult for it to react with other materials (since an increase in temperature increases possibility of a reaction).

Answer:

s = 19.23 m

Explanation:

Since, the frictional force is given as:

f = μN = μW

f = μmg   ----------- equation (1)

but, from Newton's 2nd Law:

f = ma   -------------- equation (2)

comparing equation (1) and equation (2):

ma = μmg

a = μg

here,

a = acceleration of puck

μ = coefficient of static friction = 0.13

g = -9.8 m/s² (negative sign for slowing down of puck)

Therefore,

a = (0.13)(-9.8 m/s²)

a = -1.274 m/s²

Now, using 3rd equation of motion:

2as = Vf² - Vi²

where,

s = distance covered = ?

Vf = Final Velocity = 0 m/s (since, puck finally stops)

Vi = Initial Velocity = 7 m/s

Therefore,

2(- 1.274 m/s²)s = (0 m/s)² - (7 m/s)²

s = (- 49 m²/s²)/(- 2.548 m/s²)

s = 19.23 m
