Hola, me pueden ayudar con física. 2. ¿ al cabo de cuanto tiempo adquiere un móvil una velocidad de 30 m / s, si parte del reposo y su aceleracion es de 3 m / s * 2?

Explanation:

The question says that, "After how long does a mobile acquire a speed of 30 m / s, if it starts from rest and its acceleration is 3 m / s*2"

Initial speed is 0

Final speed is 30 m/s

Acceleration a = 3 m/s²

It is required to find time when it acquire a speed of 30 m/s. Using equation of kinematics as :

So, after 10 seconds it will acquire a speed of 30 m/s.

where are the vectors ?
