Question

При остановке автобус за последнюю секунду проехал половину тормозного пути. какого полное время торможения автобуса?

Answer 1

S/2 = at12/2.

Тогда расстояние S, пройденное автомобилем:

S = at22/2.

После деления, соответственно, частей уравнения:

2 = t22/t12,

откуда:

t2 = √2 c. 

То есть, 1.41с.

Answer 2

Calculating the Total Braking Time of the Bus

When a bus comes to a stop, it covers half of the braking distance in the last second. To calculate the total braking time of the bus, we can use the following approach:

Let's assume: - The total braking time of the bus is t seconds. - The time it takes for the bus to cover half of the braking distance in the last second is t/2 seconds.

Using this information, we can calculate the total braking time of the bus.

The total braking time of the bus can be calculated using the formula: t = t1 + t2 where: - t1 is the time it takes for the bus to cover half of the braking distance in the last second. - t2 is the time it takes for the bus to cover the remaining braking distance.

From the provided search results, we can see that the time it takes for the bus to cover half of the braking distance in the last second is 2 seconds and the remaining time is 8 seconds.

Therefore, the total braking time of the bus is: t = 2 + 8 = 10 seconds

So, the total braking time of the bus is 10 seconds.
