Question

Два лучника, стоя рядом выстрелили в одном направлении. Стрела первого лучника летела со Скоростью 5 м/с, а стрела второго 3м/с.Какое расстояние будет между ними, когда первая стрела пролетит 50 м?

Answer 1

50/5=10 секунд полёта
3*10=30м пролетела вторая стрела
50-30=20м растояние между ними

Answer 2

Между ними будет 20 метров

Answer 3

Calculating the Distance Between Two Archers' Arrows

To calculate the distance between the two archers when the first arrow has traveled 50m, we can use the formula for distance, speed, and time.

Given: - Speed of the first arrow, v1 = 5 m/s - Speed of the second arrow, v2 = 3 m/s - Distance traveled by the first arrow, d = 50 m

We can use the formula: distance = speed × time

Calculating the Time Taken by the First Arrow

First, we need to calculate the time taken by the first arrow to travel 50m. We can use the formula: time = distance / speed

For the first arrow: time taken by the first arrow, t1 = 50 m / 5 m/s = 10 s

Calculating the Distance Traveled by the Second Arrow

Now, we can calculate the distance traveled by the second arrow in 10 seconds, using the formula: distance = speed × time

For the second arrow: distance traveled by the second arrow, d2 = 3 m/s × 10 s = 30 m

Finding the Distance Between the Arrows

The distance between the two arrows when the first arrow has traveled 50m is the difference between the distance traveled by the second arrow and the initial distance between the arrows.

distance between the arrows = d2 - d = 30 m - 50 m = -20 m

The negative value indicates that the second arrow has not yet reached the initial position of the first arrow when it has traveled 50m.

Therefore, the distance between the two arrows when the first arrow has traveled 50m is -20 meters.
