Question

Автомобиль "Ламборгини", масса которого составляет 1720 кг (вместе с водителем) разгоняется с 0 км/ч до 180 км/ч за 5 сек.Определите силу,сообщающую автомобилю ускорение

Answer 1

F = ma

180 км/ч = 50 м/с

a = (V - Vo) / t

F = m * (V - V0) / t =  1720 * (50 - 0) / 5 = 17200 Н

Answer 2

разгоняется с 0 км/ч до 180 км/ч за 5 сек

ускорение а =(v-vo) /t= (50-0) /5=10 v|c2

сила F=ma=1720*10=17200 H = 17,2 кН

Answer 3

Calculation of the Force

To determine the force required to accelerate the Lamborghini from 0 km/h to 180 km/h in 5 seconds, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m * a).

Given: - Mass of the Lamborghini (including the driver): 1720 kg - Time taken to accelerate: 5 seconds - Initial velocity: 0 km/h - Final velocity: 180 km/h

First, we need to convert the velocities from km/h to m/s, as the SI unit for acceleration is meters per second squared (m/s^2).

Converting the initial velocity: 0 km/h = 0 m/s

Converting the final velocity: 180 km/h = 50 m/s

Next, we can calculate the acceleration using the formula: Acceleration (a) = (Final velocity - Initial velocity) / Time taken

Substituting the values: Acceleration (a) = (50 m/s - 0 m/s) / 5 s = 10 m/s^2

Now, we can calculate the force using Newton's second law: Force (F) = Mass (m) * Acceleration (a)

Substituting the values: Force (F) = 1720 kg * 10 m/s^2 = 17,200 N

Therefore, the force required to accelerate the Lamborghini from 0 km/h to 180 km/h in 5 seconds is 17,200 Newtons
