What speed does the car gain when accelerating with an acceleration of 0.4 m / s2 for 10 s if the initial speed of the car was 10 m / s
Ten seconds after acceleration, the car will acquire a speed equal to v = at, a – acceleration, t time.
In our case, it will be – 0.4 m / s² * 10 s = 4 m / s.
The formula for the total speed for uniformly accelerated motion is determined by the formula – v = v start + at, where v start is the initial speed, a is the acceleration, t is the time.
The initial speed of our car is given to us as 10 m / s.
Therefore, during acceleration, 10 seconds after its start, the speed of our car will be equal to – 10 m / s + 4 m / s = 14 m / s.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
