Question

Мяч упал с высоты 3М отскочил от пола и был пойман на высоте 1 м Найдите путь и перемещение мяча

Answer 1

Перемещение: 2м
Путь: 4м
Перемещение- минимальный путь от начала движения к конечной точке
Путь- длина траектории

Answer 2

Problem Analysis

We are given that a ball falls from a height of 3 meters, bounces off the floor, and is caught at a height of 1 meter. We need to find the path and displacement of the ball.

Path of the Ball

To find the path of the ball, we need to consider the ball's motion before and after the bounce.

Before the bounce: - The ball falls from a height of 3 meters.

After the bounce: - The ball rebounds from the floor and reaches a height of 1 meter.

Therefore, the path of the ball can be represented as follows: - The ball falls from a height of 3 meters to the floor. - The ball rebounds from the floor and reaches a height of 1 meter.

Displacement of the Ball

To find the displacement of the ball, we need to consider the change in position from the starting point to the ending point.

The starting point is the initial height of the ball, which is 3 meters. The ending point is the height at which the ball is caught, which is 1 meter.

Therefore, the displacement of the ball is the difference between the starting and ending points: - Displacement = Ending point - Starting point - Displacement = 1 meter - 3 meters - Displacement = -2 meters

The negative sign indicates that the ball has moved downwards from its starting point.

Summary

In summary, the path of the ball involves falling from a height of 3 meters, bouncing off the floor, and reaching a height of 1 meter. The displacement of the ball is -2 meters, indicating that it has moved downwards from its starting point.
