Question

Чему равно ускорение автомобиля , если через 2 минуты после начала движения из состояния покоя он приобрел скорость 72км/час система СИ: 2 мин=120с 72км/ч=20м/с

Answer 1

V = at
a = v/t =>  a = 2/120 = 0.16 м/с2 ( примерно )

Answer 2

Calculating the Acceleration of the Car

To calculate the acceleration of the car, we can use the formula:

Acceleration = (Final Velocity - Initial Velocity) / Time

Given: - Initial velocity (u) = 0 m/s (since the car starts from rest) - Final velocity (v) = 20 m/s (converted from 72 km/h to m/s) - Time (t) = 120 seconds (2 minutes)

Using the given values, we can calculate the acceleration:

Acceleration = (20 m/s - 0 m/s) / 120 s

Acceleration = 20 m/s / 120 s

Acceleration = 0.1667 m/s^2

Therefore, the acceleration of the car is 0.1667 m/s^2.
