Question

Автомобиль движется по прямой с ускорением 2 м/с в квадрате без начальной скорости. Путь, который он проходит за первые 5 секунд движения, равен

Answer 1

В этом случае S=a*t^2/2=2*25/2=25 м

Answer 2

Calculating the Distance Traveled by the Car

To calculate the distance traveled by the car in the first 5 seconds of motion, we can use the following kinematic equation: distance = initial velocity * time + 0.5 * acceleration * time^2

Given: - Initial velocity (u) = 0 m/s (as the car starts from rest) - Acceleration (a) = 2 m/s^2 - Time (t) = 5 seconds

Using the above values in the kinematic equation, we can calculate the distance traveled by the car.

Calculation

Using the kinematic equation: distance = 0 * 5 + 0.5 * 2 * 5^2

distance = 0 + 0.5 * 2 * 25

distance = 0 + 0.5 * 50

distance = 0 + 25

distance = 25 meters

Therefore, the car travels a distance of 25 meters in the first 5 seconds of motion.
