Moving uniformly accelerated from a state of rest, the car covered the distance s = 28m for the time interval delta t = 4 s. what is the vehicle acceleration modulus
To determine the modulus of constant acceleration of a given vehicle, we use the formula: S = V0 * t + a * t ^ 2/2, where S is the distance traveled (S = 28 m); V0 – initial speed (V0 = 0, since the movement began from a state of rest); t – elapsed time (t = 4 s).
Since V0 = 0 m / s, the formula used will take the form: S = a * t ^ 2/2, whence a = 2S / t ^ 2.
Let’s perform the calculation: a = 2 * 28/4 ^ 2 = 3.5 m / s2.
Answer: The module of acceleration of a given vehicle is 3.5 m / s2.
