The car starts off with an acceleration of 0.5 m / s. what is the speed of the car in 0.5 minutes?

The car starts to move, which means that its initial speed of movement: v 0 = 0 m / s. It is known from the problem statement that the car was moving with acceleration: a = 0.5 m / s ^ 2. To determine what the vehicle speed will be in t = 0.5 min = 30 s, we will use the definition of acceleration:

a = (v – v₀): t, then, v = v₀ + a ∙ t.

Let’s substitute the values of physical quantities in the calculation formula and find the speed to which the car will accelerate:

v = 0 m / s + 0.5 m / s ^ 2 ∙ 30 s;

v = 15 m / s.

Answer: the car will accelerate in 0.5 minutes to a speed of 15 m / s.
