Question

Через какое время остановмтся автомобиль имеющий в начале движения скорость 10 м/с и движущийся равнозамедленно с ускорением 2 м/с

Answer 1

Через 20 секунд автомобиль остановится

Answer 2

Calculating the time taken to stop

The initial speed of the vehicle is 10 m/s and it is decelerating uniformly with an acceleration of 2 m/s^2. To calculate the time taken to stop the vehicle, we can use the kinematic equations of motion for uniform acceleration:

`v = u + at` `s = ut + (1/2)at^2`

Where: v = Final velocity u = Initial velocity a = Acceleration t = Time s = Displacement

Given: u = 10 m/s (Initial velocity) a = -2 m/s^2 (Deceleration)

Using the first equation: v = u + at 0 = 10 + (-2)t t = 5 s

So the time taken for the vehicle to come to a stop is 5 seconds.
