Question

Под действием силы тяги F1 = 2000 H автобус проехал определенное растояние .Оставшийся путь автобус преодолел под действием силы F2=1,6 кН .во сколько раз первая часть пути больше второй если механическая работа выполненная на первом отрезке пути в два раза больше чем та что была выполнена на втором отрезке пути

Answer 1

Из условия разницы работ А1/ А2=2  ⇒F1*s1/F2*s2=2
s1/s2=2*F2/F1=2*1600/2000=1.6  первый отрезок пути в 1,6 раза больше второго

Answer 2

Calculation of the Ratios of the Distances Traveled

To solve this problem, we need to calculate the ratio of the distances traveled by the bus under the influence of two different forces. Let's denote the distance traveled under the force F1 as D1 and the distance traveled under the force F2 as D2.

Given: - Force F1 = 2000 H (H stands for hectonewtons, which is equivalent to 100 newtons) - Force F2 = 1.6 kN (kN stands for kilonewtons, which is equivalent to 1000 newtons)

We need to find the ratio D1/D2.

To calculate the ratio, we can use the concept of work done. The work done by a force is equal to the product of the force and the distance traveled in the direction of the force.

Let's assume that the work done on the first part of the journey (under the force F1) is W1, and the work done on the second part of the journey (under the force F2) is W2.

Given: - W1 = 2 * W2 (the work done on the first part of the journey is twice the work done on the second part of the journey)

We know that the work done is equal to the force multiplied by the distance traveled. Therefore, we can write the following equations:

W1 = F1 * D1 W2 = F2 * D2

Substituting the given values, we have:

2000 * D1 = 2 * 1.6 * D2

Simplifying the equation, we get:

D1 = (2 * 1.6 * D2) / 2000 D1 = (3.2 * D2) / 2000 D1 = 0.0016 * D2

Therefore, the ratio D1/D2 is 0.0016.

Answer: The first part of the distance traveled is 0.0016 times greater than the second part of the distance traveled.

Please note that the given question does not provide specific values for the distances traveled or the time taken. We have only calculated the ratio of the distances traveled based on the given information.
