Question

Помогите пожалуйста (Физика 9 класс), как найти место встречи двух тел, какая формула, желательно не графическим способом, ибо на рисунках обычно не точно показывается величина.

Answer 1

Чтобы найти место встречи, нужно сначала определить время встречи. Это можно сделать аналитически (расчетами).
Для этого необходимо приравнять уравнения движения. 
Например, x₁=x₂
Привести подобные, вычислить время встречи. А после, подставить время встречи в любое из исходных уравнений, и получится координата (место) встречи.

Finding the Meeting Point of Two Objects in Physics

To find the meeting point of two objects in physics, you can use the formula for finding the meeting point of two objects moving towards each other. The formula is:

Meeting Point = (Distance traveled by the first object * Speed of the second object) / (Speed of the first object + Speed of the second object)

This formula allows you to calculate the point at which two objects, moving at different speeds, will meet.

Let's break down the components of this formula: - Distance traveled by the first object: This refers to the distance covered by the first object until the meeting point. - Speed of the second object: This represents the speed at which the second object is moving. - Speed of the first object: This denotes the speed at which the first object is moving.

By plugging in the appropriate values for these variables, you can calculate the meeting point of the two objects.

For example, if the first object travels a distance of 100 meters at a speed of 20 m/s, and the second object travels at a speed of 15 m/s, you can use the formula to find their meeting point.

Meeting Point = (100 * 15) / (20 + 15)

This will give you the point at which the two objects will meet.
