Question

Бақылаушы биік таудың баурайынан 200м қашықтықта тұр.Қанша уақыттан кейін ол өзінің қатты дауыстаған сөзінің жаңғырығын естиды?Дыбыстың таралу жылдамдығын 340м/с деп есептеңдер.

Answer 1

S-200m
V-340 m\s
t-?
V=S\t
t=S\t--> 200/340=0.58
Жаңғырықты есту үшін дыбыс жерге жетіп шағылып қайтып келу керек сонда 0,58*2=1,16 сек

Answer 2

The Distance and Speed of a Falling Object

When an object falls freely under the influence of gravity, its distance from the starting point and its speed can be calculated using certain formulas. In this case, we have a falling object that is initially 200 meters above the ground, and we want to determine how long it takes for the object to reach the ground and the final velocity it reaches.

To calculate the time it takes for the object to fall, we can use the formula:

time = sqrt((2 * distance) / acceleration)

where: - distance is the initial distance the object is from the starting point (in this case, 200 meters), - acceleration is the acceleration due to gravity (approximately 9.8 m/s^2).

Using this formula, we can calculate the time it takes for the object to fall:

time = sqrt((2 * 200) / 9.8) ≈ 6.42 seconds [[1]].

Therefore, it takes approximately 6.42 seconds for the object to fall from a height of 200 meters.

To calculate the final velocity of the falling object, we can use the formula:

final velocity = initial velocity + (acceleration * time)

In this case, the object starts from rest, so the initial velocity is 0 m/s. Using the acceleration due to gravity of 9.8 m/s^2 and the calculated time of 6.42 seconds, we can calculate the final velocity:

final velocity = 0 + (9.8 * 6.42) ≈ 62.92 m/s [[2]].

Therefore, the object reaches a final velocity of approximately 62.92 m/s when it hits the ground.

Please note that these calculations assume no air resistance and that the object is falling in a vacuum. In reality, air resistance can affect the motion of objects falling through the atmosphere, so these calculations provide an idealized scenario.
