When accelerating for 10 seconds, the car acquires a speed of 54 km / h. What is the acceleration of the car?

We consider the movement of the car to be uniformly accelerated (the acceleration of the car is constant).

Vehicle speed can be represented using the formula:

V = V0 + at, where V is the vehicle speed after acceleration (V = 54 km / h = 54 / 3.6 = 15 m / s), V0 is the initial speed (we assume that the car started accelerating from a standstill; V0 = 0 m / s), a – acceleration (m / s2), t – acceleration time (t = 10 s).

Let’s calculate the acceleration:

V = 0 + at = at.

a = V / t = 15/10 = 1.5 m / s2.

Answer: The acceleration of the car during acceleration is 1.5 m / s2.

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.
