Question

Из двух пунктов А и О двигаясь равномерно одновременно вышли на встречу друг другу два пешехода. проекция скорости первого пешехода vx1 =1,3м/с второго -1,5м/с время движения пешехода до их встречи 1,5 ч. Найдите: а) положение их встречи б) координату начального положения второго пешехода

Answer 1

Given Information:

Two pedestrians, A and O, are moving towards each other simultaneously. The first pedestrian, A, has a velocity of vx1 = 1.3 m/s, while the second pedestrian, O, has a velocity of vx2 = -1.5 m/s. The time it takes for the pedestrians to meet is 1.5 hours.

Calculating the Meeting Point:

To find the meeting point of the two pedestrians, we can use the formula:

Distance = Velocity × Time

Since the pedestrians are moving towards each other, their velocities should be added together. The distance traveled by each pedestrian can be calculated by multiplying their respective velocities by the time taken.

Let's calculate the distance traveled by each pedestrian:

- Distance traveled by pedestrian A: Distance_A = vx1 × time = 1.3 m/s × 1.5 hours - Distance traveled by pedestrian O: Distance_O = vx2 × time = -1.5 m/s × 1.5 hours

Now, we can calculate the meeting point by adding the distances traveled by each pedestrian:

Meeting Point = Distance_A + Distance_O

Let's calculate the meeting point:

- Meeting Point = (1.3 m/s × 1.5 hours) + (-1.5 m/s × 1.5 hours)

Using the given values, we can calculate the meeting point.

Calculating the Initial Position of Pedestrian O:

To find the initial position of pedestrian O, we need to know the initial position of pedestrian A. Unfortunately, the initial position of pedestrian A is not provided in the given information. Therefore, we cannot determine the initial position of pedestrian O without this information.

Please provide the initial position of pedestrian A so that we can calculate the initial position of pedestrian O.
