Question

Мяч подброшен вертикально вверх,со скоростью 14, 2 м/с. Найдите путь и модуль перемещения мяча,за 2 секунды движения

Answer 1

S = v0 t - g t^2 / 2; s = 14.7 *2 - 10 *4/ 2 = 9.4 m . Поднялся на 29, 4 м и одновременно опустился на 20 м

Answer 2

Calculation of the Path and Displacement of a Ball Thrown Vertically Upwards

To calculate the path and displacement of a ball thrown vertically upwards with an initial velocity of 14.2 m/s over a period of 2 seconds, we can use the equations of motion and the principles of projectile motion.

First, let's calculate the path of the ball. When the ball is thrown vertically upwards, it follows a parabolic path. At the highest point of its trajectory, the ball momentarily comes to rest before falling back down. The path of the ball can be represented by a vertical line.

Next, let's calculate the displacement of the ball. Displacement is a vector quantity that represents the change in position of an object. In this case, the displacement of the ball can be calculated by subtracting the initial position from the final position.

Since the ball is thrown vertically upwards and comes back down to its initial position, the displacement of the ball is zero. This means that the ball ends up at the same position from where it was thrown.

In summary: - The path of the ball is a vertical line. - The displacement of the ball is zero.
