Путь (S) равен 0 метру, а перемещение (r) равно 2 метрам

Answer 2

Problem Analysis

A ball is thrown upwards to a height of 1 meter and then caught again. We need to determine the distance traveled and the displacement of the ball.

Solution

To solve this problem, we need to understand the concepts of distance and displacement.

Distance is the total length of the path traveled by an object. It is a scalar quantity and is always positive.

Displacement is the change in position of an object. It is a vector quantity and can be positive, negative, or zero.

In this case, the ball is thrown upwards and then caught again at the same position. Therefore, the displacement of the ball is zero.

The distance traveled by the ball can be calculated by considering the distance covered during the upward journey and the distance covered during the downward journey.

During the upward journey, the ball covers a distance equal to the height it was thrown, which is 1 meter.

During the downward journey, the ball covers the same distance as the upward journey. Therefore, the total distance traveled by the ball is twice the height it was thrown, which is 2 meters.

To summarize: - The displacement of the ball is zero. - The distance traveled by the ball is 2 meters.

Conclusion

The ball has a displacement of zero and travels a distance of 2 meters.
