Question

Автомобиль трогаясь с места с постоянным ускорением,через 3 секунды набрал скорость 15 м/с. каково ускорение автомобиля?

Answer 1

Дано:

t = 3 c

v₀ = 0 м/с

v = 15 м/с

----------------

а - ?

 

Формула:

$a = \frac{v - v_{0}}{t}$

Решение:

$a = \frac{15 m/s - 0 m/s}{3 s} = 5 \frac{m}{s^{2}}$

Ответ: а = 5 м/с²

Answer 2

t=3c

V1=0

V2=15м с

a=V2-V1/t=15-0/3=5 мс 

Answer 3

Calculation of Acceleration

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

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t)

Given that the car starts from rest and reaches a velocity of 15 m/s in 3 seconds, we can substitute the values into the formula:

Acceleration (a) = (15 m/s - 0 m/s) / 3 s

Simplifying the equation:

Acceleration (a) = 15 m/s / 3 s

Therefore, the acceleration of the car is 5 m/s².
