Question

1. Скорость автомобиля за 5 секунд уменьшается c vo - 25 м / с до v - 5 м / с . Найти проекцию ускорения автомобиля .​

Answer 1

Ответ:

дано V0=25 м/с V=5 м/с t=5 с S- ?

S=(V+Vo)*t/2

S=30*5/2=75 м

Ответ S=75 м

Объяснение:

не знаю точно,но по моему так

Answer 2

Calculation of the Car's Acceleration Projection

To find the projection of the car's acceleration, we need to use the formula:

a = (vf - vi) / t

where: - a is the acceleration - vf is the final velocity - vi is the initial velocity - t is the time interval

In this case, the initial velocity (vi) is 25 m/s, the final velocity (vf) is 5 m/s, and the time interval (t) is 5 seconds.

Substituting the values into the formula, we get:

a = (5 m/s - 25 m/s) / 5 s

Simplifying the equation, we have:

a = (-20 m/s) / 5 s

Calculating the value, we find:

a = -4 m/s²

Therefore, the projection of the car's acceleration is -4 m/s².
