Question

Кінь біжить по колу циркової арени. Період його руху дорівнює 8 секунд, діаметр арени-13 метрів. Визначте (приблизно) швидкість руху коня.

Answer 1

0.62 метри на секунду

Answer 2

Calculating the Horse's Speed

To calculate the speed of the horse running around the circus arena, we can use the formula for speed:

Speed (V) = Distance (S) / Time (T)

Given: - Time (T) = 8 seconds - Diameter of the arena (D) = 13 meters

We can calculate the distance the horse travels in one lap around the arena using the formula for the circumference of a circle:

Circumference (S) = π * Diameter (D)

Substituting the given values: S = π * 13

Now, we can calculate the speed of the horse.

Calculation

Using the given formula for speed: V = S / T

Substituting the values: V = (π * 13) / 8

Using the value of π as approximately 3.14: V ≈ (3.14 * 13) / 8

Calculating: V ≈ 40.78 / 8 V ≈ 5.1 meters per second

So, the approximate speed of the horse running around the circus arena is 5.1 meters per second.
