Question

Машина за 10 секунд разгоняется до 100км/ч какое ей нужно расстояние что бы разогнаться до 100км/ч

Answer 1

Переведем 100км/ч в м/с
100км/ч=100000м/ч=100000/3600 м/с=250/9 м/с
значит ускорение а=v/t=250/9/10=25/9 м/с^2
закон расстояния гласит S=S0+V0t+at^2/2. У нас S0=V0=0. Значит за 10 секунд машина пройдет 25/9*10^2 /2=25*50/9=1250/9≈138,9м
ответ. приблизительно 138.9м

Answer 2

Calculating Distance for Acceleration

To calculate the distance required for a car to accelerate to 100 km/h in 10 seconds, we can use the formula:

distance = (initial velocity * time) + (0.5 * acceleration * time^2)

Where: - initial velocity = 0 (assuming the car starts from rest) - time = 10 seconds - acceleration = final velocity / time

Using the given final velocity of 100 km/h, we can convert it to m/s for the calculation.

Calculation

The final velocity of 100 km/h can be converted to m/s: - 100 km/h = 27.78 m/s

Now, we can calculate the acceleration: - acceleration = 27.78 m/s / 10 s - acceleration = 2.78 m/s^2

Substitute the values into the distance formula: - distance = (0 * 10) + (0.5 * 2.78 * 10^2) - distance = 0 + (0.5 * 2.78 * 100) - distance = 0 + (0.5 * 278) - distance = 0 + 139 - distance = 139 meters

So, the car would need approximately 139 meters to accelerate to 100 km/h in 10 seconds.
