Question

Автомобиль массой 2 тонны,трогаясь с места,прошел путь 100 метров за 100 секунд.Найдите силу тяги

Answer 1

Дано:                                       Решение

m=2т=2000кг                    a=2S/t²    a=2×100/100²      a=0,02м\с²

S=100м                             F=ma       F=2000×0,02=40Н

t=100с

F-?

Answer 2

Calculation of Traction Force

To find the traction force of a car, we can use the equation:

F = (m * V^2) / (2 * S)

Where: - F is the traction force - m is the mass of the car - V is the velocity of the car - S is the distance traveled

In this case, the car has a mass of 2 tons, which is equivalent to 2000 kilograms. The car traveled a distance of 100 meters in 100 seconds.

Substituting the given values into the equation, we have:

F = (2000 * V^2) / (2 * 100)

Simplifying further:

F = 10 * V^2

To find the value of V, we can use the formula:

V = S / t

Where: - V is the velocity - S is the distance traveled - t is the time taken

Substituting the given values into the equation, we have:

V = 100 / 100

Simplifying further:

V = 1 m/s

Now, substituting the value of V into the equation for F:

F = 10 * (1^2)

Simplifying further:

F = 10 Newtons

Therefore, the traction force of the car is 10 Newtons.
