Question

Автомобиль двигается с ускорением 0,2 м/с² в течение 10 секунд после начала движения. Какой скорости он достиг?

Answer 1

V0 = 0
V = V0 +at = 0 + 0.2*10 =2 м/с

Answer 2

Calculation of Final Velocity

To calculate the final velocity of the car, we can use the formula:

Final velocity (v) = Initial velocity (u) + (Acceleration (a) * Time (t)).

Given that the car starts from rest (initial velocity, u = 0), the acceleration is 0.2 m/s², and the time is 10 seconds, we can substitute these values into the formula:

Final velocity (v) = 0 + (0.2 m/s² * 10 s) = 2 m/s.

Therefore, the car reaches a final velocity of 2 m/s after 10 seconds of acceleration.
